check for existence of file

j-me · 07-28-2003, 02:11 PM

How can I determine if a file exists in a directory?

I'm trying to re-write an old 6.2 script that does not work on RH8.0. A file get ftp'd from the mainframe to this server. A cron job runs @the 20th of every hour to see if the file exists, If it does, then it manipulates the file and prepares for processing.

Code:

if test -e /home/me/myfile
then
mv /home/me/myfile /home/you/send/

I hit enter accidentally.

cp /home/me/myfile /home/you/backup/$DAY/

fi

if [ -f /home/me/myfile ]
then
echo found
fi

j-me · 07-28-2003, 02:52 PM

#!/bin/sh
if [ -f /home/me/myfile ]
then
echo 'found'
fi

i get : No such file or directory.

but if i go to the directory, ls shows the file.
# ls
myfile

if i remove the #!/bin/sh
: unexpected end of file
hmm?

Still very much in the infancy of shell scripting land and better way to do i guess but that worked for me

Quote:

if find /home/me/myfile >/dev/null 2>&1
then
echo file found
fi

okay, here's results.

I had ftpd this from the 6.2 box to 8.0 box. So I decided to just retype the whole bloody script fresh in a new file. By golly they both worked. The error was referencing an error past the last line of the script which did not make sense. That's why I decided to retype it thinking something happened in the ftp process.

Anyway, it now appears to work just peachy.

Thanks for input.

Cheers!
