quick one: cut'ing or seding directory path to get just the filename

Bill McNAMARA_1 — Thu, 18 Oct 2001 09:28:00 GMT

Hi all,

If I have a variable $F
that looks something like the following:
/usr/bin/dothis.ksh
and or
/usr/contrib/bin/dothat.ksh

what's the best way to extract the filename
echo $F | nice -and -sweet

Thanks!
Bill

How about using the basename command? Is that what you're looking for?

I guess I should have been a bit more descriptive...i.e.

FILENAME=$(basename $F)

not sure if this is a requirement, but you can also strip of the suffix,i.e.:

if $F=/usr/contrib/bin/something.ksh

FILENAME=$(basename $F .ksh)

$FILENAME should be set to the word something.

nice one santosh,
That was just what I was looking for..

It would have saved me so much pain if I knew about that around a year ago!!

Thanks again,
Bill

You're welcome.

Also just FYI, you can use the dirname command to get the directory part of the full path. Its complimentary to the basename command.

Hi,

something I learned yesterday from this forum:
This solution will not cover filenames with blanks! Enclose $F in double quotes !

# echo $F
/tmp/a b c
# FILENAME=$(basename "$F")
# echo $FILENAME
a b c
#

basename works and is easy to remember, for efficiency you may try using the quick shell construct:

NewPath=${F##*/}

(Essentially NewPath = $F but remove the largest section from the front of F which matches the glob '*/')

(shell should be efficient :-)

I did not know about dirname and basename either. I ended up doing this:

LIST=`echo "$1" | sed 's#/# #g' `
for I in $LIST
do
LASTI=$I
done
echo $LASTI

Where $1 is your fullpath'd file /a/b/c/file1
.....or as said above: basename $1
