I want to trim this string /tmp/files/ from a variable $FILES
For example:
setenv FILES=/tmp/files/list
ONLY_L=`trim($FILES,'/tmp/files/')`
echo $ONLY_L
#should see only 'list'
I though of using sed for the job, but it look a little "ugly" because all the \ that came before the /.
For sed, you don't have to use /
For instance, this works as well:
echo $FILES | sed 's#/tmp/files/##'
ONLY_L="${FILES##*/}"
or
ONLY_L="$(basename "$FILES")"
or
ONLY_L="$(echo "$FILES" | sed 's|.*/||')"
does what you want
You should use the basename command for this. It automatically removes the path and leaves just the filename:
basename /tmp/files/list
Output:
list
You don't need sed or call tools. bash provides you this ability using string substitution.
$ FILES='/tmp/files/list'
# do this
$ echo "${FILES/\/tmp\/files\/}"
list
# or this
$ echo "${FILES##*/}"
list
setenvis acshcommand, not abashcommand.
