simple,

Code:
basename /usr/local/sbin/sshd
dirname /usr/local/sbin/sshd

For the above said output, command is

Code:
echo "Path to be set as: `basename /usr/local/sbin/sshd`"
echo "Command to be set as : `dirname /usr/local/sbin/sshd`"

oh yes...!!
i had forgotten these two commands....thanks !!

now lets try something else...

we have something like this:

Code:
/usr/sbin/rsct/bin/rmcd -a IBM.LPCommands -r

i need to spilt this as :

path:/usr/sbin/rsct/bin/
command:rmcd
arguments:-a IBM.LPCommands -r

i guess `dirname` would work but how about basename?

its interesting to see how to get those arguments as well...

Regards
Abhi

There is no need to use external commands.

Code:
path=/usr/local/sbin/sshd
echo ${path##*/}
echo ${path%/*}

How I do it, Don't know how correct it is though. Thoughts???
Code:
cmdline='/usr/sbin/rsct/bin/rmcd -a IBM.LPCommands -r'
path=${cmdline%/*}     # Path
tmp=${cmdline##*/}     # Filename & Arguments
fname=${tmp%% *}       # Filename - Wish it could be nested... :) fname=${${cmdline##*/}%% *}
args=${tmp#${fname} *} # Arguments

echo ${path}    # Path
echo ${fname}   # Filename
echo ${args}    # Arguments

-Enjoy

Read the parameter expansion section of your shell's man page, and look at the examples already given. They contain the techniques you need.
