Shell Programming and Scripting

works fine for me in '/bin/ksh' under Solaris - make sure you specify the proper shell interpreter on the first line [as I posted originally].

hmm.. I stripped all the code, essentially leaving just:

Code:

while read RECORD; do
 echo "RECORD->[${RECORD}]"
done < ${PIRFE_CSV_PATH}PEURO03496.1118769614122

There are other, similar files, I tried to put them into the read loop as well.
For some reason, the shell script hangs when it gets to the while loop for these files. I think the problem may be with the files themselves, not the code.. The files can't be too large, only about 100-300 lines, each with 32 "fields"..

All the variables are working as they should. System just hangs when it gets to the while. I'm still trying to figure out why it hangs... I'll keep this post updated. It's just a typical CSV file with each line being one record.

I don't think it's permissions, all users have at least read permissions:
-rwxr--r--

make sure your FILENAME is not a directory

I'm certain it's a file, and not a directory since I can view it in my text editor as a regular csv file.
In "ls -al" there's no "->" link to somewhere else.

From the same directory, I can run commmands like:

cat PEURO03497.1118773120982
and
more PEURO03497.1118773120982

and it opens fine.

This is a long shot but let me try renaming the file.

run this and see where it gets stuck.... change the name/path of 'file_names.txt' as needed.

Code:

#!/bin/ksh

FIELD1='PBR'
FIELD2=' '

#typeset -i count
while read FILENAME; do
  while read RECORD; do
    if [ "$FIELD1" = 'PBR' -a "$FIELD2" = ' ' ]; then
        count=$(($count + 1))
        echo "file->[$FILENAME] count->[${count}]"
    fi
  done < $FILENAME
done < file_names.txt

I enabled "set -vx" so we can see what's going on as it's running... here's the output. (note: i simplified the ls command output..)

This is where it gets stuck/hangs. Then I have to use kill command to terminate.

The first filename in file_names.txt is "PEURO03497.1118773120982"
I only put two file names into that txt file.. and I copied both files into the same dir as the script. I also tried switching the order in the txt file, same result. The shell let's me do more and cat on them just fine.

I think we've isolated everything except the file contents... perhaps the actual csv data is conflicting in some way.

what IS the content of file_names.txt [EXACTLY]?
make sure you have no control characters: neither in your script or in the file_names.txt files.
