how to remove a particular word from a string in Shell scripting

[onlynimal]

I have a variable saying $remaining having value as "/etc /var /sns /vol"(which is assigned at runtime)

i want to check whether '/sns' is present in that string. If yes, it should be removed and then the string must be like $remaining="/etc /var /vol"
is there any command available to check for particular substring and remove that.
Plz help.Thnx in advance

remaining="/etc /var /sns /vol"
remaining=`echo $remaining | sed "s/\/sns //g"`

Hi.

Also for bash:

#!/bin/sh

# @(#) s1       Demonstrate bash pattern matching in variable contents.

set -o nounset
echo
echo "GNU bash $BASH_VERSION" >&2
echo

remaining="/etc /var /sns /vol"
echo " variables remaining = :${remaining/??sns/}:"

exit 0

producing:

% ./s1

GNU bash 2.05b.0(1)-release

 variables remaining = :/etc /var /vol:

(with help from O''Reilly Learning the bash Shell, 2nd, pages 99 ff) ... cheers, drl
