Need help modifying my script

wc -c `find . -path '*/sample/*.txt'`

ozo, but it will not loop through all fielsystems, will it?

The thing is I have a number of different filesystems: /u01, /u02, /u03, /u04 and many more. I need to loop through them because almost every one of them have word "sample" in it

i get an error

find: 0652-017 -path is not a valid option.

Also wc command counts the characters not file size, I know it is basically the same thing but I feel like it is not the right way to go.

The bottom line this code does not work either way

A command to generate the result could be:

find /u0? -type f | grep "/${var}/.*\.txt$" | xargs ls -s | awk '{c+=$1};END { print c }'

Select allOpen in new window

To get this into a variable, use

totsize=$(find /u0? -type f | grep "/${var}/.*\.txt$" | xargs ls -s | awk '{c+=$1};END { print c }')

Select allOpen in new window

(editted to add the "-type f", in case a directory name ended with ".txt")

du -ch `find / -type d -name sample`

you should try and toy with the find command to make it faster. maybe something like this

du -ch `find /u* -maxdepth 4 -type d -name sample`

i guess you can figure that part out easily if you know where to expect the files

if locate is available and reasonably up to date, you may want to replace find with "locate sample"

simon3270, your code produces an error:

find: 0652-019 The status on /u0? is not valid.

That's /u zero questionmark (or whatever matches the base directories you want to search)

yes, I tried /u zero question mark and that's what gave me the error. I also tried /u? but still same error

I think you get that error either if there is a problem with a disk (are they NFS mounts with a dead server?  Or actual disk failures?) or simply if the path specified doesn't exist - you don't want to try text until it works - use a pattern which finds the actual disks (assuming that /u01 or /uo1 for example is the mount point for a mounted disk).  I can't see your system, so unless you copy and paste the output, for example, or "ls -p /" or "mount", I can't see what your directories are called.

If find can't get past the lowest level directory, it won't be able to check for "sample" directories - you need to fix that problem first.

I only used /u0? because you implied that you needed to check all such directories (and I didn't expect them to be /uo?).  if you only need to check some of them, first check that the ones you want work with "find" (test them one at a time with, for example, "find /u01 | head"), then just list them on the command line, like:

    find /u01 /disk2 /cc0703 /mdisk04 -type f |

(and then the rest of the line is the same as it was).

here is an example on my machine

$ du -ch `find /v* -maxdepth 2 -type d -name \*sa\*` | tail
4,0K	/var/log/boot-sav/log/2013-06-21__14h13boot-repair20/sdb1
4,0K	/var/log/boot-sav/log/2013-06-21__14h13boot-repair20/sda5
1,1M	/var/log/boot-sav/log/2013-06-21__14h13boot-repair20/sda
4,0K	/var/log/boot-sav/log/2013-06-21__14h13boot-repair20/sda1
4,0K	/var/log/boot-sav/log/2013-06-21__14h13boot-repair20/sda2
1,2M	/var/log/boot-sav/log/2013-06-21__14h13boot-repair20
7,1M	/var/log/boot-sav/log
7,1M	/var/log/boot-sav
4,0K	/var/log/samba
7,2M	total

Select allOpen in new window

try something like this

du -ch `find /u[0-9] -maxdepth 4 -type d -name sample` | cut -d \  -f 1

Select allOpen in new window

simon, directories are called

/u01
/u02
/u10
/u40
/u80

skullnobrains, what does this part do?

cut -d \  -f 1

The command becomes:

find /u01 /u02 /u10 /u40 /u80 -type f | grep "/${var}/.*\.txt$" | xargs ls -s | awk '{c+=$1};END { print c }'

Select allOpen in new window

If that returns the same "find" error, check that each disk can be read by running:
    ls /u01 /u02 /u10 /u40 /u80 >/dev/null
and letting us know if there are any errors reported

I thought you only wanted to add up the size of the *.txt files, not of the entire contents of the directories called "sample".
