OK.

then go to corresponding directory, rename file (may need split the file as well).
May? What decides that?

below pseudocode is testing code to check I can use variable with "$" sign.
That is gibberish.
Quote:
yes, there may have more than one files matching. could you please advise the best way to handle multiple matches.
I already showed you one way, if you don't like it, perhaps you need to tell me what you're expecting to happen.

And your code still has that grep on the end which will do exactly nothing where you've put it and I don't know what you're expecting it to do if you put it anywhere else. What is it for?

command to call the script:
Code:
 ksh scriptname 'v$abc'

OK, questions remaining:
  • "variable with $" -- We already told you v$abc is not a variable, so what do you mean now?
  • Splitting the file -- when do you want this to happen, why, how?
  • Multiple matches -- what do you top expect to happen, why, how?
  • What, exactly, are you hoping that grep will do?

NAME
uri_urn - URI utilities, URN scheme SYNOPSIS
package require Tcl 8.2 package require uri::urn ?1.1.2? uri::urn::quote url uri::urn::unquote url _________________________________________________________________ DESCRIPTION
This package provides two commands to quote and unquote the disallowed characters for url using the urn scheme, registers the scheme with the package uri, and provides internal helpers which will be automatically used by the commands uri::split and uri::join of package uri to handle urls using the urn scheme. COMMANDS
uri::urn::quote url This command quotes the characters disallowed by the urn scheme (per RFC 2141 sec2.2) in the url and returns the modified url as its result. uri::urn::unquote url This commands performs the reverse of ::uri::urn::quote. It takes an urn url, removes the quoting from all disallowed characters, and returns the modified urls as its result.
