- .SH NAME
- lsearch \- See if a list contains a particular element
- .SH SYNOPSIS
- \fBlsearch \fR?\fImode\fR? \fIlist pattern\fR
- .BE
-
- .SH DESCRIPTION
- .PP
- This command searches the elements of \fIlist\fR to see if one
- of them matches \fIpattern\fR.
- If so, the command returns the index of the first matching
- element.
- If not, the command returns \fB\-1\fR.
- .VS
- The \fImode\fR argument indicates how the elements of the list are to
- be matched against \fIpattern\fR and it must have one of the following
- values:
- .TP
- \fB\-exact\fR
- The list element must contain exactly the same string as \fIpattern\fR.
- .TP
- \fB\-glob\fR
- \fIPattern\fR is a glob-style pattern which is matched against each list
- element using the same rules as the \fBstring match\fR command.
- .TP
- \fB\-regexp\fR
- \fIPattern\fR is treated as a regular expression and matched against
- each list element using the same rules as the \fBregexp\fR command.
- .PP
- If \fImode\fR is omitted then it defaults to \fB\-glob\fR.
