I think you misunderstood me, I agree with that sentiment, to a point. Smilie Actually, you might want to convert all backslashes into double-backslashes to prevent sed from eating them. You should also escape forward slashes in case there's a forward slash in ststr2, that could bomb your script. And do that for ststr1 too.

Code:
ststr2=$(sed 's/\\/\\\\/g;s/\//\\\//g' <<< "$ststr2")
ststr1=$(sed 's/\//\\\//g' <<< "$ststr1")

Ugh, that almost looks like ASCII art... Too bad there's no way I know of to just tell sed not to escape anything in the input string, that'd make this easy. Or if there is a way, my sed knowledge isn't strong enough to find it.

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5) WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.10 30 Jan 2004 script(1)
