Top Forums Shell Programming and Scripting stripping certain characters in at the middle of a string Post 302194476 by era on Tuesday 13th of May 2008 02:26:45 AM

It depends on where you get the input string from and what the separators are. If | is in the set it's tricker, but in general, to split on a set of characters, you can use set -- with IFS set to the token splitting characters. That's what I continue to suggest.

Code:
vnix$ IFS=@
vnix$ set -- `echo see@hear@touch@smell`
vnix$ echo $#
4
vnix$ echo $1
see
vnix$ echo $4
smell
vnix$ echo "$@"
see hear touch smell

I don't know how to make it any clearer than that. Now "see" is in $1, "hear" is in $2, "touch", in $3, and "smell" in $4. I think that satisfies your requirement.

If you are reading an input string from the terminal then you can add | to the set of splitting characters no problem, but you can't use it directly in a script because it's already a command separator (for setting up pipelines, no less).
