LOOK(1) | General Commands Manual | LOOK(1) |
look
— display
lines beginning with a given string
look |
[-df ] [-t
termchar] string
[file] |
The look
utility displays any lines in
file which contain string as a
prefix. As look
performs a binary search, the lines
in file must be sorted.
If file is not specified, the file /usr/share/dict/words is used, only alphanumeric characters are compared and the case of alphabetic characters is ignored.
Options:
-d
-f
-t
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.
The original manual page stated that tabs and blank characters
participated in comparisons when the -d
option was
specified. This was incorrect and the current man page matches the historic
implementation.
look

Version 7 AT&T UNIX.
