Extract the folder name that you are in

[astroumut]

Hi,

I would like to use the current folder name as a title of a text document, but I could not print out the folder name that I am in.

E.g.,

$pwd
$/Users/users/umut/mystar1

How can I extract only the name of "mystar1" and write it to a file?

Thanks a lot

here is the code that extracts the filename and prints it to stdout

i=2
while [ 1 ] ; do
    file1=`echo $PWD | cut -d "/" -s -f${i}`
    let i=i+1
    file2=`echo $PWD | cut -d "/" -s -f${i}`
    if [ "$file2" = "" ]
    then
        echo $file1
        break
    fi
done

not necessarily the easiest/best way, but it works

basename $(pwd) >file

They are both working great, thanks a lot.

Hi.

Modern shells allow forms of string extraction expressions. These are useful because they do not require external programs such basename, dirname, etc. For example with bash:

#!/usr/bin/env bash

# @(#) s3	Demonstrate emulation of old basename command.

echo
echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version "=o" $(_eat $0 $1) basename
set -o nounset

echo
mypath="/Users/users/umut/mystar1"
echo " Current directory is emulated as $mypath"

echo
echo " Final component extracted with basename:"
echo "$( basename $mypath)"

echo
echo " Final component extracted with string expression:"
echo "${mypath##*/}"

exit 0

producing:

% ./s3

(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0 
GNU bash 3.2.39
basename (GNU coreutils) 6.10

 Current directory is emulated as /Users/users/umut/mystar1

 Final component extracted with basename:
mystar1

 Final component extracted with string expression:
mystar1

One drawback is that one needs to learn the syntax, and initially it can be confusing.

See section "Parameter Expansion" in man bash ... cheers, drl
