Linux / Unix Command: lsearch

Command Library

NAME

lsearch - See if a list contains a particular element  

SYNOPSIS

lsearch ?mode? list pattern

 

DESCRIPTION

This command searches the elements of list to see if one of them matches pattern. If so, the command returns the index of the first matching element. If not, the command returns -1. The mode argument indicates how the elements of the list are to be matched against pattern and it must have one of the following values:

-exact

The list element must contain exactly the same string as pattern.

-glob

Pattern is a glob-style pattern which is matched against each list element using the same rules as the string match command.

-regexp

Pattern is treated as a regular expression and matched against each list element using the rules described in the re_syntax reference page.

If mode is omitted then it defaults to -glob.
