Shell Programming and Scripting

code tags are like this.

[ code]
some text that will remain indented
[ /code]

(i puted some space after the [ cause i cant find a way to escape the tag itself :P)
about your script, i dont see the error....

hi broli,

do i need a search Path ?

if i do, then how should i get the search path?

"All shell scripts should include a search path specification:

PATH=/usr/ucb:/usr/bin:/bin; export PATH

A PATH specification is recommended -- often times a script will fail for some people because they have a different or incomplete search path.

The Bourne Shell does not export environment variables to children unless explicitly instructed to do so by using the export command. "

I don't think the PATH is the problem, the "done" error means something funny is in the file. You seem to be using DOS file names; are you using Cygwin? Is /usr/bin/bash the correct path to the Bash interpreter? Maybe try with /bin/sh there instead. Also try bash -vx new.sh and post the output here.

By the by, here is an equivalent script without the while loop:

Code:

find . -name '*.FMT' | xargs gawk -F '\t' '$2== "MS2" {print $1, $2}'

Note: you should have a space between "find ." and "-name '*.FMT'"

This is really weird, as I mentioned earlier, the find command doesn't have an output with tab separated fields.
I've asked several times to post the output of the find command and the desired output but I've give it up.

Hi Era,


Thank you so much, the xargs did the job.No problems

I am using cygwin. Can please help on how to check the correct path to the Bash interpreter?

Here is the output of "bash -vx new.sh"

$ bash -vx new.sh
#!/usr/bin/sh
find . -name '*.FMT' | while read line
do
gawk -F '\t' '$2== "MS2" {print $1, $2}' $line
done
new.sh: line 5: syntax error near unexpected token `done'
new.sh: line 5: `done'

There maybe non-printing characters in your script. Highlight them by running your script through cat and post its output here that is...

Code:

cat -vet your_script

This is out.


$ cat -vet new.sh
#!/bin/sh^M$
find . -name '*.FMT' | while read line^M$
do^M$
gawk -F '\t' '$2== "MS2" {print $1, $2}' $line^M$
done
