|
||
.SH NAME
|
||
strcmp \(en compare strings
|
||
.\"
|
||
.SH SYNOPSIS
|
||
|
||
strcmp
|
||
.RM [ string ]
|
||
.RB [ strings... ]
|
||
.\"
|
||
.SH DESCRIPTION
|
||
|
||
Check whether string arguments are the same.
|
||
.\"
|
||
.SH DIAGNOSTICS
|
||
|
||
The program will exit successfully if the strings are identical. Otherwise, it
|
||
exits with the value 1 if an earlier string has a greater byte value than a
|
||
later string (e.g. strcmp b a) and 255 if an earlier string has a lesser byte
|
||
value (e.g. strcmp a b).
|
||
|
||
When invoked incorrectly, a debug message will be printed and the program will
|
||
exit with the appropriate
|
||
.BR sysexits.h (3)
|
||
error code.
|
||
.\"
|
||
.SH CAVEATS
|
||
|
||
The program will exit unsuccessfully if the given strings are not identical;
|
||
therefore, Unicode strings may need to be normalized if the intent is to check
|
||
visual similarity and not byte similarity.
|
||
.\"
|
||
.SH RATIONALE
|
||
|
||
The traditional tool for string comparisons in POSIX and other Unix shells has
|
||
been
|
||
.BR test (1).
|
||
This tool also handles integer comparisons and file scrutiny. These parts of its
|
||
functionality have been broken out into multiple utilities.
|
||
|
||
This program’s functionality may be performed on a POSIX-compliant system with
|
||
.BR test (1p).
