-.TH LOOK "1" "June 2011" "util-linux" "User Commands"
-.SH NAME
-look \- display lines beginning with a given string
-.SH SYNOPSIS
-.B look
-[\fIoptions\fR] \fIstring \fR[\fIfile\fR]
-.SH DESCRIPTION
-The 
-.B look
-utility displays any lines in
-.I file
-which contain
-.I string
-As
-.B look
-performs a binary search, the lines in
-.I file
-must be sorted (where sort(1) got the same options \-d and/or \-f
-that
-.B look
-is invoked with).
-.PP
-If
-.Ar file
-is not specified, the file
-.Pa /usr/share/dict/words
-is used, only alphanumeric characters are compared and the case of
-alphabetic characters is ignored.
-.SH OPTIONS
-.TP
-\fB\-a\fR, \fB\-\-alternative\fR
-Use alternative dictionary file.
-.TP
-\fB\-d\fR, \fB\-\-alphanum\fR
-Dictionary character set and order, i.e. only alphanumeric characters are
-compared. (On by default if no file is specified).
-.TP
-\fB\-f\fR, \fB\-\-ignore\-case\fR
-Ignore the case of alphabetic characters. (On by default if no file is
-specified).
-.TP
-\fB\-t\fR, \fB\-\-terminate\fR=\fIC\fR
-Specify a string termination character, i.e. only the characters
-in string up to and including the first occurrence of termchar
-are compared.
-.TP
-\fB\-V\fR, \fB\-\-version\fR
-Output version information and exit.
-.TP
-\fB\-h\fR, \fB\-\-help\fR
-Display help screen and exit.
-.PP
-The look utility exits 0 if one or more lines were found and displayed, 1 if
-no lines were found, and >1 if an error occurred.
-.SH EXAMPLE
-.nf
-sort -d /etc/passwd -o /tmp/look.dict
-look -t: root:foobar /tmp/look.dict
-.nf

-.IP "\fB/usr/share/dict/web2\fR" 4
-the alternate dictionary
-.SH "SEE ALSO"
-.BR grep (1),
-.BR sort (1)
-.SH COMPATIBILITY
-The original manual page stated that tabs and blank characters participated
-in comparisons when the alphanum option was specified. This was incorrect
-and the current man page matches the historic implementation.
-.SH HISTORY
-The
-look
-utility appeared in Version 7 AT&T Unix.
-.SH AVAILABILITY
-The look command is part of the util-linux package and is available from
-ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
