script question - if file exists

[Jim Mickens]

Is there any way in a shell script to check for the existence of a specific file?

[Steven Sim Kok Leong · Accepted solution]

Hi,

Use the -e flag.

#!/sbin/sh
if [ -e $file ]
then
echo $file exists
else
echo $file does not exist
fi

Hope this helps. Regards.

Sure:

if [ -r ${FNAME} ]
then
echo "File ${FNAME} exists"
else
echo "File ${FNAME} not found"
fi

man test for details.

in a while:


while [ -f /tmp/file ] ;do
.
.
.
done

Thanks to all. I had a user ask me, and since I'd never tried it before, I had no idea. I'll forward this info to him.

If you have the Unix In A Nutshell book, look at the page on test, it will give you about 20 different tests that you can use such as -f for file -x for executable file ...

But -f should work for what you asked.

use the test flags:

-e = exists
-f = plain file
-r = readable file
-d = directory

if [ -r file_name]; then
(do stuff here)
fi

Hi Jim,

The following common flags can be used:

-r file --> if file exists & is readable
-w file --> if file exists & is writable
-x file --> if file exists & is executable
-f file --> if file exists & is not a directory
-d file --> if file exists & is a directory
-s file --> if file exists & size > 0
