Top Forums UNIX for Beginners Questions & Answers Check that at least one file exists in the directory. Post 303039527 by Peasant on Wednesday 9th of October 2019 01:18:55 AM

Don't think array here is required, as well as a testing if file(s) exists.
Only in some corner cases, if file is deleted during program execution..
Is that your case ?

Will this fill your requirment :
Code:
INPUTDIR=/path/with/files
for i in $INPUTDIR/abc*.dat
do
        echo "$i" # action on existing file, here echo.
done

Hope that helps
Regards
Peasant.
