Returning a "0" if folder is empty
Hi All,

I am trying to force a "0" value if a folder is empty.
Is there any unix command i can make use of to force a "0" (zero) ?
i tried to use " grep -c * " but the error is " no match "

Code:
$ grep -c "string" *
grep: 0652-033 Cannot open *.
$ echo $?
2

Code:
grep -c "string" *
if [ $? -eq 2 ]; then
    exit 0
fi

Hi anbu,


I tried to use " grep -c XXX /mycomp/unix/scripts/TEMP " where /mycomp/unix/scripts/TEMP is my empty folder with no files inside.

However, when there's files inside it will output a zero too.

PLs help

hi,

try this.

ls -l folder_name > temp_file
x=`cat 2`
echo $x
grep -c "total 0" 2
echo $?
rm 2

Hi
What does $? represent ?
There's an error "Variable syntax" for this "$?".
