Problem setting arguments in script

[sar26]

I'm fairly new to scripting and I'm trying to create a batch script to run another script. I've copied these scripts from others which work and have modified them, but I've got a problem with the input arguments not being recognised properly. The scripts are written in csh. The script setup is:

Script to run batch:

#!/bin/csh -f
foreach file (`cat /files/file_list.txt`)
set name = `echo $file | awk '{print substr($1,1,14)}'`
set scale = `echo $file | awk '{print substr($1,16,3)}'`
/folder/scripts/process.csh $name $scale
end

The file_list.txt contains the list of files which need to be processed and a scale # that's required. Each row contains the info for each file.

If I echo the $name and $scale, they come up properly.


The process.csh script:

#!/bin/csh -f
if ($#argv < 2) then
cat << End_Usage
Usage: process.csh <name> <scale>
name: name of data file (.dat file)
scale: scale interval (#)
End_Usage
exit 1
else if ($#argv == 2) then
set input=$1
set int=$2
set output_file=out_$1
endif
endif

....rest of script


Initially I created the scripts with just the $name argument and it worked, but found later that I also needed the $scale argument.

After adding the $scale argument, it isn't recognised properly and the process.csh script tries to use this argument for $input instead of $int.

I'm not sure what's wrong with the script, its probably a simple fix, but I can't work it out! Any advice would be appreciated!

did you try to quote the args

try
set name = `echo '$file' | awk '{print substr($1,1,14)}'`

notice the quotes around file

I tried it and it didn't work. It displays the message related to < 2 arguments.

okay, managed to fix it. I recreated the text file in a different format (replaced spaces with commas) and that solved the problem.
