UNIX for Dummies Questions & Answers

How do I test the return condition in the script if no files are found:

for file in `Find ${LANDING_FILE_DIR}${BTIME_FILENAME_PATTERN}`

do
...
..
done

I want to capture the return code so I can echo the error or condition. Using if [[ $# -eq 0 ]] always returns zero no matter where it's placed.

are you looking for something like:

if [ -e $filename] then
...


this will check if the file exists.

I do the following a check for -s and -r. The find statment in the for loop issues a bad status:

find: bad status-- /home/rnitcher/test/BTIME_ACTUAL_WORK_HRS_wk_[0-9][0-9]_to_[0-9][0-9].csv

I need to capture this return from the find command and exit the program cleanly.

maybe i'm not fully understanding what you're trying to do here... always possible!

you want to see what the return code is of a condition?

yes I think so.


...
for file in `find ${LANDING_FILE_DIR}${bTIME_FILENAME_PATTERN1}`

do
....

running the script I get the following find error:

find: bad status-- /.../BTIME_ACTUAL_WORK_HRS_wk_[0-9][0-9]_to_[0-9][0-9].csv

so I'm looking for a way in the script to capture the fact that no file(s) where found and not just have the script abort with the the find: bad status message....
