Please use the code tags as required per forum rules.

You were close with your awk script, try removing the last instance of new line ("\n"), so it becomes:

Code:
echo `awk '{if ($1 ~ /^[a-z]*[0-9][0-9][0-9]/) print NR, $0, "\n"}' tmp.lst` > tmp4.lst

For me this outputs:

Code:
1 abcd456|1|23123|123123|23423

3 xxxd999|d|adfdfs|adfadf|adfdasfadf

Or, you could simply use:

Code:
awk -F"|" '$1~/[0-9][0-9][0-9]/' tmp.lst` > tmp4.lst

Tcl_StringMatch(3)					      Tcl Library Procedures						Tcl_StringMatch(3)

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern SYNOPSIS
#include <tcl.h> int Tcl_StringMatch(string, pattern) int Tcl_StringCaseMatch(string, pattern, nocase) ARGUMENTS
char *string (in) String to test. char *pattern (in) Pattern to match against string. May contain special characters from the set *?[]. int nocase (in) Specifies whether the match should be done case-sensitive (0) or case-insensitive (1). _________________________________________________________________ DESCRIPTION
This utility procedure determines whether a string matches a given pattern. If it does, then Tcl_StringMatch returns 1. Otherwise Tcl_StringMatch returns 0. The algorithm used for matching is the same algorithm used in the ``string match'' Tcl command and is similar to the algorithm used by the C-shell for file name matching; see the Tcl manual entry for details. | In Tcl_StringCaseMatch, the algorithm is the same, but you have the option to make the matching case-insensitive. If you choose this (by | passing nocase as 1), then the string and pattern are essentially matched in the lower case. KEYWORDS
match, pattern, string Tcl 8.1 Tcl_StringMatch(3)
