UNIX for Dummies Questions & Answers

I'm sure this can't be too tough, but.

I want to check the existance of file(s) by extension. There may be 0,1,N files. If any files exist, then remove them.

Thanks for any insight.

well this is pretty crude but gets the job done:

Code:

ls | grep *.txt > file1 && while read FILES ; do rm $FILES ; done < file1 && rm file1

I am sure there is a way to do it without using another file but I am too new to know how...

edit: this should be obvious, but if it isn't replace txt with extension of your choice

Thank you, I'll try this. In the meantime, I found this works:

for file in $BaseDir/* ; do
case $file in
*.sql)
rm $file;;
*.in)
rm $file;;
blah.*)
rm $file;;
check.output.*)
rm $file;;
esac
done

Since my script is in a cron job, it does not leave mail if it doesn't find the files.

Thanks again,
Paul

Code:

find /path -name \( -name '*.in' -o -name '*.sql' \) -exec rm -f {} \;
