STRIP(1)STRIP(1)NAMEstrip - strip symbol table, debugging and line number information from
an object file
SYNOPSISstrip [-lVx] file...
DESCRIPTION
The strip command removes the symbol table SHT_SYMTAB and its associ‐
ated string table, debugging information, and line number information
from ELF object files. That is, besides the symbol table and associated
string table, the following sections are removed:
.line
.debug*
.stab*
Once this stripping process has been done, limited symbolic debugging
access is available for that file. Therefore, this command is normally
run only on production modules that have been debugged and tested.
If strip is executed on a common archive file (see ar.h(3HEAD)) in
addition to processing the members, strip removes the archive symbol
table. The archive symbol table must be restored by executing the ar(1)
command with the -s option before the archive can be linked by the
ld(1) command. strip produces appropriate warning messages when this
situation arises.
strip is used to reduce the file storage overhead taken by the object
file.
OPTIONS
The amount of information stripped from the ELF object file can be
controlled by using any of the following options. The following options
are supported:
-l
Strip line number information only.Does not strip the symbol ta‐
ble or debugging information.
-V
Prints, on standard error, the version number of strip.
-x
Does not strip the symbol table. Debugging and line number infor‐
mation might be stripped.
OPERANDS
The following operand is supported:
file
A path name referring to an executable file.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables
that affect the execution of strip: LANG, LC_ALL, LC_CTYPE, LC_MES‐
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0
Successful completion.
>0
An error occurred.
FILES
/tmp/strp*
Temporary files

The symbol table section is not removed if it is contained within a
segment or if the file is a relocatable object.
The line number and debugging sections are not removed if they are con‐
tained within a segment or if their associated relocation section is
contained within a segment.
The strip command is used to remove a standard predefined set of sec‐
tions from an ELF object file. To remove a user specified section by
name, see mcs(1).
