Hey all!
After a couple of hours of searching, I've decided that both my
scripting-foo and my google-foo are weak this morning, so I turn to you
folks for a quick answer.
In a bash script, I'm trying to create a directory and test if it is
successful.
The man page doesn't indicate what mkdir returns as a successful code,
but I have a vague impression (being a non-programmer) that a return
code of zero is generally considered success and non-zero is generally
considered failure. (So man-page writer, hint hint ...)
Here's the relevant snippet of code I have so far:
===
echo "Does target directory '$targetDir' exist?"
if [ -d $targetDir ]
then
echo "YES, '$targetDir exists!"
echo
else
echo "No, '$targetDir' does not exist."
echo
echo "Attempting to create $targetDir"
echo
if [ mkdir -p $targetDir ] # If the mkdir fails
then
echo "Failed to create directory. Aborting."
exit 1
else
echo "Created $targetDir directory
successfully!"
fi
fi
===
When I run this, I get this output:
===
Does target directory '/TERASTATIONBACKUP/GOSHEN/2008/OCTOBER' exist?
No, '/TERASTATIONBACKUP/GOSHEN/2008/OCTOBER' does not exist.
Attempting to create /TERASTATIONBACKUP/GOSHEN/2008/OCTOBER
/usr/local/bin/BackupGoshenHome: line 57: [: -p: binary operator expected
Created /TERASTATIONBACKUP/GOSHEN/2008/OCTOBER directory successfully!
Tarring up source into target
/TERASTATIONBACKUP/GOSHEN/2008/OCTOBER/2008-Oct-28.tgz
===
I've tried various permutations of the test case - put it in
double-quotes, in single-quotes, put a bang in front of the text, remove
the brackets, add a semi-colon at the end of the test line before the
comment, etc, but can't figure out what I'm doing wrong.
Thanks for any help!
