Bash script to parse the Windows version written inside the license.rtf

If it is in the third line always then you can use the script below
i=0
while read line
do
      if [ $i -eq 3 ]
      then
            echo "$line"
      fi
      i=`expr $i + 1`
done < winver.txt

here winver.txt is the file to read

An alternate can be

cat winver.txt | grep "WINDOWS"

but this will return all the lines containing WINDOWS (all caps)

I like the option n.2. I've tried to parse the eula.txt of windows XP with this command :

mario@mario-desktop:/media/FREEDOS/sh$ cat eula.txt | grep "Microsoft Windows"

Microsoft Windows XP Home Edition

I need to store the output "Microsoft Windows XP Home Edition" inside a variable

and I've tried to parse the license.rtf of Windows Vista / Seven with this command :

cat license.rtf | grep "WINDOWS"

\pard\brdrb\brdrs\brdrw10\brsp20 \nowidctlpar\sb120\sa120 WINDOWS 7 ULTIMATE\par
mario@mario-desktop:/media/FREEDOS/sh$

in this case I need to store inside a variable the output : WINDOWS 7 ULTIMATE

inside a script you can always store output into a variable using the command in `` (acutes)


temp = `cat licence.rtf | grep "WINDOWS"`
echo $temp
this should store the the value of the commands (in your case "WINDOWS 7 ULTIMATE")  to the variable temp

cat licence.rtf | grep "WINDOWS" returns nothing,because Rich text is a kind of markup language, similar to html. What you see in the display is not exactly the text the file itself contains. The parsing would have to take this into account.

errata corrige :

cat licence.rtf | grep "WINDOWS" returns * nothing that I can use as is *

ah sure... then may be you can use cut to get the output. Do not have a linux box right now to test it but you can do something like below
cat licence.rtf | grep "WINDOWS" | cut -d\ -f8
here -d\ is used for delimiter as "\"
-f8 is for field 8 after cut is performed, so this should return the output.

you can also use awk for this.

mario@mario-desktop:/media/FREEDOS/sh$ cat license.rtf | grep "WINDOWS" | cut -d\ -f8

error : cut: delimiter must be a single character.

use it in single quotes '\'

mario@mario-desktop:/media/FREEDOS/sh$ cat license.rtf | grep "WINDOWS" | cut -d'\' -f8

this is the beginning of the license.rtf file :

use -f9 or -f10 or may be -f7.. here number after f represents the column you want.

mario@mario-desktop:/media/FREEDOS/sh$ cat license.rtf | grep "WINDOWS" | cut -d'\' -f9

sa120 WINDOWS 7 ULTIMATE

mario@mario-desktop:/media/FREEDOS/sh$ cat license.rtf | grep "WINDOWS" | cut -d'\' -f10

par

the first should be good,but I have to cut "sa120"

i can also see a space "sa120 WINDOWS 7 ULTIMATE" so you need to do another cut after getting this string like

cat license.rtf | grep "WINDOWS" | cut -d'\' -f9 | cut -d' ' -f2
here ' ' is space

mario@mario-desktop:/media/FREEDOS/sh$ cat license.rtf | grep "WINDOWS" | cut -d'\' -f9 | cut -d' ' -f2
WINDOWS

has been cut exactly what I want : "7 ULTIMATE"

Bingo,you "won" 500 points :D

mario@mario-desktop:/media/FREEDOS/sh$ cat license.rtf | grep "WINDOWS" | cut -d'\' -f9 | cut -d' ' -f "2 3 4"
WINDOWS 7 ULTIMATE

btw sh scripting is a kind of language I have because you have to pay your attention over aspects frankly not so important and you can't pay attention over the whole piece of code.

*I hate*

ver_windows=$(cat /mnt/sda1/Windows/system32/eula.txt | grep "Microsoft Windows")
echo $ver_windows

Microsoft Windows XP Home Edition

if [ "$ver_windows" = "Microsoft Windows XP Home Edition" ]; then ver_windows_min="xp"
echo home
fi

output : nothing

I think that $ver_windows is not = to "Microsoft Windows XP Home Edition" ,why ?

Try this
if [ $ver_windows -eq "Microsoft Windows XP Home Edition" ]
then
    ver_windows_min="xp"
    echo $home
fi

FIXED : there was a stupid hidden space at the end of the first line.
