|
.SH SYNOPSIS
|
|
|
|
strcmp
|
|
.RM [ string ]
|
|
.RB [ strings... ]
|
|
|
|
.SH DESCRIPTION
|
|
|
|
Strcmp checks whether the given strings are the same.
|
|
Strcmp exits successfully if the strings are identical. Otherwise, strcmp exits
|
|
with the value 1 if an earlier string has a greater byte value than a later
|
|
string (e.g.
|
|
.R strcmp b a
|
|
)
|
|
and 255 if an earlier string has a lesser byte value (e.g.
|
|
.R strcmp a b
|
|
).
|
|
|
|
.SH DIAGNOSTICS
|
|
|
|
Strcmp will print an error message and exit unsuccessfully with a status
|
|
described in sysexits(3) if used incorrectly (given less than two operands).
|
|
|
|
.SH UNICODE
|
|
|
|
Strcmp will exit unsuccessfully if the given strings are not identical;
|
|
Unicode strings may need to normalized if the intent is to check visual
|
|
similarity and not byte similarity.
|
|
|
|
.SH STANDARDS
|
|
|
|
Strcmp is not described in POSIX.1-2017.
|
|
Strcmp's function may be performed on a purely POSIX system with test(1).
