.SH NAME
strip
\(em remove unnecessary information from strippable files
(\fBDEVELOPMENT\fP)
.SH SYNOPSIS
.LP
.nf
strip \fIfile\fR...
.fi
.SH DESCRIPTION
A strippable file is defined as a relocatable, object, or executable
file.
On XSI-conformant systems, a strippable file can also be an archive
of object or relocatable files.
.P
The
.IR strip
utility shall remove from strippable files named by the
.IR file
operands any information the implementor deems unnecessary for
execution of those files. The nature of that information is
unspecified. The effect of
.IR strip
on object and executable files shall be similar to the use of the
.BR \-s
option to
.IR c99
or
.IR fort77 .
The effect of
.IR strip
on an archive of object files shall be similar to the use of the
.BR \-s
option to
.IR c99
or
.IR fort77
for each object file in the archive.
.SH OPTIONS
None.
.SH OPERANDS
The following operand shall be supported:
.IP "\fIfile\fR" 10
A pathname referring to a strippable file.
.SH STDIN
Not used.
.SH "INPUT FILES"
The input files shall be in the form of strippable files successfully
produced by any compiler defined by this volume of POSIX.1\(hy2017
or produced by creating or updating an archive of such files
using the
.IR ar
utility.
.SH "ENVIRONMENT VARIABLES"
The following environment variables shall affect the execution of
.IR strip :
.IP "\fILANG\fP" 10
Provide a default value for the internationalization variables that are
unset or null. (See the Base Definitions volume of POSIX.1\(hy2017,
.IR "Section 8.2" ", " "Internationalization Variables"
for the precedence of internationalization variables used to determine
the values of locale categories.)
.IP "\fILC_ALL\fP" 10
If set to a non-empty string value, override the values of all the
other internationalization variables.
.IP "\fILC_CTYPE\fP" 10
Determine the locale for the interpretation of sequences of bytes of
text data as characters (for example, single-byte as opposed to
multi-byte characters in arguments).
.IP "\fILC_MESSAGES\fP" 10
.br
Determine the locale that should be used to affect the format and
contents of diagnostic messages written to standard error.
.IP "\fINLSPATH\fP" 10
Determine the location of message catalogs for the processing of
.IR LC_MESSAGES .
.SH "ASYNCHRONOUS EVENTS"
Default.
.SH STDOUT
Not used.
.SH STDERR
The standard error shall be used only for diagnostic messages.
.SH "OUTPUT FILES"
The
.IR strip
utility shall produce strippable files of unspecified format.
.SH "EXTENDED DESCRIPTION"
None.
.SH "EXIT STATUS"
The following exit values shall be returned:
.IP "\00" 6
Successful completion.
.IP >0 6
An error occurred.
.SH "CONSEQUENCES OF ERRORS"
Default.
.LP
.IR "The following sections are informative."
.SH "APPLICATION USAGE"
None.
.SH EXAMPLES
None.
.SH RATIONALE
Historically, this utility has been used to remove the symbol table
from a strippable file. It was included since it is known that the
amount of symbolic information can amount to several megabytes; the
ability to remove it in a portable manner was deemed important,
especially for smaller systems.
.P
The behavior of
.IR strip
on object and executable files is said to be the same as the
.BR \-s
option to a compiler. While the end result is essentially the same,
it is not required to be identical.
.P
XSI-conformant systems support use of
.IR strip
on archive files containing object files or relocatable files.
.SH "FUTURE DIRECTIONS"
None.
