grep multiple commands

[Elizabeth H]

Hi

Below is what I am trying to do. I have a variable which contains a list of commands seperated by ":". While trying to use a for loop to get each command, it doesnt retrun the correct results

Example:

var="command -1:command -2*: command something*"
for c in `echo $var | tr ':' ' '`
do
  echo $c
done

Instead of getting the below
command -1
command -2*
command something

I get
command
-1
command
-2*
command
something

Please help

Hi i am providing the answer using Perl programming,can u just check u r language also,there must be a split command ,u use that command u get output as u required manner.

$var="command -1:command -2*: command something*";
@commands = split(/:/,$var);
foreach $comm (@commands) {

print " $comm \n ";
}

if there is any chance don't have any split funtion in u r language ,please use regular expression
