shell script to be debugged

seems to work - i modified it a bit, that you can also use it with .tar.gz files:

#!/bin/bash

file_name="your-tar-gz-name.tar.gz"

file_size=`gunzip -l $file_name | awk '{ print $2 }' | grep -v uncompressed`
# Getting the exact file size in bytes
filekb=`echo "$file_size/1024" | bc`
# converting that into kilobytes
ini_fs_size=`df -k . | awk '{ print $3 }' | grep -v Used`
# getting the current filesystem size where your extracting
# the file .

percentage=0
final_percent=100
tar -xzf $file_name &

{
while [ "$percentage" -lt $final_percent  ]
do
    latter_fs_size=`df -k . | awk '{ print $3 }' | grep -v Used`
    # After extracting started get the filesystem size every second
    # and the do a small math
    percent_val=`expr $latter_fs_size - $ini_fs_size`
    # Get the difference between intial and current filestem space
    percentage=`echo "($percent_val * 100)/$filekb" | bc`
    # get the precentage of it with respect to original file size
    if [ "$percentage" -gt $final_percent ]
    then
        echo $final_percent
    else
        echo $percentage
    fi
    # the above if loop si to cover up just in case
    sleep 1
done
} | dialog --gauge "Uncompressing status" 6 70 0

Pencil123:
    What is wrong with the script .It was working fine before right? are you getting any errors .

AndyWHv:
    it is not making any difference gauge or guage .


surya.

to debug your script use inside (wher you want debugging to be started):

set -x

oh...maybe i know what your problem is....is it that you can't see that there is a progress on small files ?

you could change the sleep to
sleep 0.1

so it will show up more often

still the script isnt working, it just stops with cursor blinking

has any1 checked and tested the script

i hv mentioned the problem at the beginning itself

surya_prabhakar : its not working

it just hangs
the n i hv to do a ctrl-c

please use
  set -x

and then tell us wher it hangs

"its not working" and "it just hangs" are useless infomration, please be more specific so we can help you

k found the problem
the filename directory shouldnt exists

i found the bug

thanx for trying

lol

: [: : integer expression expected

Yes! if it already exists - the filesystem size is same before and now hence the progress bar will not move .

surya.

please do what ahoffmann said . need more information  :-)

(test -z "$file_name" || test -z "$filekb" || test -z "$ini_fs_size" || test -z "$latter_fs_size")&& exit 1

ok sorry for that
i need it for extracting .war files also

i replaced tar -xzf $file_name & with
   jar -xf $file_name &

its giving some integer expression expected

what to do

war files ????????

> its giving some integer expression expected
> what to do
more and more your comments get anoying ...
how should we help you if you don't provide detailed infomation?
What is the problem with copy&paste the error messages verbatim?
why do you not follow the suggestions?

well i think thats what i did

the only problem i have now is extracting .wat files
they stand for web archive

ok here i will paste the whole code
#!/bin/sh

file_name="somefile.war"

file_size=`ls -l $file_name | awk '{ print $2 }' | grep -v uncompressed`
# Getting the exact file size in bytes
filekb=`echo "$file_size/1024" | bc`
# converting that into kilobytes
ini_fs_size=`df -k . | awk '{ print $3 }' | grep -v Used`
# getting the current filesystem size where your extracting
# the file .

percentage=0
final_percent=100
jar -xzf $file_name &

{
while [ "$percentage" -lt $final_percent  ]
do
    latter_fs_size=`df -k . | awk '{ print $3 }' | grep -v Used`
    # After extracting started get the filesystem size every second
    # and the do a small math
    percent_val=`expr $latter_fs_size - $ini_fs_size`
    # Get the difference between intial and current filestem space
    percentage=`echo "($percent_val * 100)/$filekb" | bc`
    # get the precentage of it with respect to original file size
    if [ "$percentage" -gt $final_percent ]
    then
        echo $final_percent
    else
        echo $percentage
    fi
    # the above if loop si to cover up just in case
    sleep 1
done

i hope this is clear enuf

sorry i m under a lot of pressure
also i havent had sleep properly
i m tring my best
i hv pasted the whole code
now it shud work with .war files aswell
plz take a look at it

if i put
            jar -x $file_name &
i get this


│Runtime error (func=(main), adr=9): Divide by zero            │  │
                           │  └──────────────────────────────────────────────────./test.sh: line 27: [: : integer expression

well i guess no ones gonna help me now

 i m sorry

pencil123, please reread http:#13457305
then sit down and think about it
then read again http:#13457305
try to understabnd it, if in doubt about any question there, ask what's the problem about it

we can't help you if you don't give the requested information

to fix your errors see http:#13452688  and http:#13457084
all answers have been given, if it does not work for you you made a mistake, typed it wrong or whatever. Dot.

i put set -x
since i m using dialog i cant see the errors

also i do get this
 Runtime error (func=(main), adr=9): Divide by zero
what does it mean

all i want now is that the script should work with .war files

but it isnt

thats all ineed

please make the script work with .war files

thats all i need

> Runtime error (func=(main), adr=9): Divide by zero
does your jar command work from command-line with that file?

can anyone help me now

i cant make the problem more clear

i dont think u need any sort of info , u have the script , make it work with .war files

.war files are web archive files
jar extraction utility is used for that

what else info is needed

> Runtime error (func=(main), adr=9): Divide by zero
does your jar command work from command-line with that file?

yes it does work from the command line

just so u know

all i want is that the script should work with .war files
that   dot war

.WAR
and jar is a utility used for extracting war files

run this ... it creates an output file called out_file in the same directory . paste the contents of the file here

#!/bin/sh
file_name="somefile.war"
file_size=`ls -l $file_name | awk '{ print $2 }' | grep -v uncompressed`
echo "file size is .....$file_size"  >> out_file
filekb=`echo "$file_size/1024" | bc`
echo "file size in kb ..... $filekb" >> out_file
ini_fs_size=`df -k . | awk '{ print $3 }' | grep -v Used`
echo "Inital fs size ...... $ini_fs_size" >> out_file
percentage=0
final_percent=100
jar -xvf $file_name &
{
while [ "$percentage" -lt $final_percent  ]
do
    latter_fs_size=`df -k . | awk '{ print $3 }' | grep -v Used`
    echo "latter fs size .... $latter_fs_size" >> out_file
    percent_val=`expr $latter_fs_size - $ini_fs_size`
    echo "percent  val is ....$percent_val" >> out_file
    percentage=`echo "($percent_val * 100)/$filekb" | bc`
    echo "percentage value ....$percentage" >> out_file
    if [ "$percentage" -gt $final_percent ]
    then
        echo $final_percent
    else
        echo $percentage
    fi
    sleep 1
done
} | dialog --gauge "Uncompressing status" 6 70 0
clear

forgot ....
> jar -xvf $file_name &
change it to
jar -xf $file_name &

file size is .....
file size in kb .....
Inital fs size ...... 10939584
latter fs size .... 10939584
percent  val is ....0
percentage value ....

wiht jar -xf $filename &

file size is .....
file size in kb .....
Inital fs size ...... 10939592
latter fs size .... 10939592
percent  val is ....0
percentage value ....

Why did you change the shell from bin/bash to bin/sh . dont change the below script except for the filename
save it as file and put permissions as
#chmod 755 <filename>  and then run it as
# ./filename    ( before you do this - remove the previously existing directory )

-------------------------------------------------------------------
#!/bin/bash
file_name="filename.war"
file_size=`ls -l $file_name | awk '{ print $5 }'`
filekb=`echo "$file_size/1024" | bc`
ini_fs_size=`df -k . | awk '{ print $3 }' | grep -v Used`
percentage=0
final_percent=100
jar -xf $file_name &

{ while [ "$percentage" -lt $final_percent  ]
do
  latter_fs_size=`df -k . | awk '{ print $3 }' | grep -v Used`
  percent_val=`expr $latter_fs_size - $ini_fs_size`
  percentage=`echo "($percent_val * 100)/$filekb" | bc`
  if [ "$percentage" -ge $final_percent ]
  then
    echo $final_percent
  else
    echo $percentage
  fi
  sleep 1
done } | dialog --gauge "A Progress bar" 6 70 0
clear
-------------------------------------------------------------------

i did as u said

but when i ran it
it said line number 18 has some problem
i check line number 18
it is
  if [ "$percentage" -ge $final_percent ]

also i can get the whole error output since i m using dialog
i m sorry

listen ... cool down for a minute - if u be in constant pressure u will commit basic mistakes .

first check the above script with tar file and tell whether it is working or not . Then we can think of jar .
script errors to be avoided first . This exact script is working firne for me ...

it works fine for tar files
no problems with that

it doesnt work with war files
thats the only problem left

ahoffmann

that is not a problem
i m running it with
file_size=`ls -l $file_name | awk '{ print $5 }'`
when i say

jar -x filename.war in command line
it extracts fine

the problem is in the script
when i try to do the same

it works fine with .jar as well
i know that

but i need to work it with .war(web archive)
.jar is for java archive

.war  files are used to package a web application directory  structure
ofcourse they do contain java files and stuff
but thats not the pont

please try getting a .war file from somewhere and try to check it

thanks
