For loop to read folder which are not under processing
Hi,

I want to read folders which do not have a file "processing" in a for loop ordered by timestamp.
Currently im doing like this.

Like
Code:
cd /home/working
for i in `ls -c1`
do
some command...
done

I want to exclude folders which have that "processing" file.
The directory contains only directories.

Thanks,
Chetan.C

Command substitution is almost always the wong way to get a list of files. Instead, feed the output of ls to a loop:
Code:
ls -c |
 while IFS= read -r dir
 do
   [ -e "$dir/processing" ] && continue ## do nothing if processing file exists
   : do whatever with directories containing "processing"
 done
