.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
utility is used to manipulate comment sections in an ELF object.
|
||
|
|
If a command-line argument
|
||
|
|
.Ar file
|
||
|
|
names an
|
||
|
|
.Xr ar 1
|
||
|
|
archive, then
|
||
|
|
.Nm
|
||
|
|
will operate on the ELF objects contained in the archive.
|
||
|
|
.Pp
|
||
|
|
By default
|
||
|
|
.Nm
|
||
|
|
operates on the ELF section named
|
||
|
|
.Dq .comment .
|
||
|
|
This may be changed using the
|
||
|
|
.Fl n
|
||
|
|
option.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
utility supports the following options:
|
||
|
|
.Bl -tag -width ".Fl a Ar string"
|
||
|
|
.It Fl a Ar string
|
||
|
|
Append the text in
|
||
|
|
.Ar string
|
||
|
|
to the comment section.
|
||
|
|
This option may be specified multiple times.
|
||
|
|
.It Fl c
|
||
|
|
Compress the comment section by removing duplicate entries.
|
||
|
|
.It Fl d
|
||
|
|
Delete the comment section from the ELF object.
|
||
|
|
.It Fl h | Fl -help
|
||
|
|
Display a usage message and exit.
|
||
|
|
.It Fl n Ar name
|
||
|

Operate on the section named
|
||
|
|
.Ar name .
|
||
|
|
.It Fl p
|
||
|
|
Print the contents of the comment section.
|
||
|
|
This step is taken after actions specified by the
|
||
|
|
.Fl a
|
||
|
|
and
|
||
|
|
.Fl c
|
||
|
|
options (if any) are completed.
|
||
|
|
.It Fl V | Fl -version
|

.Sh COMPATIBILITY
|
||
|
|
The behavior of the
|
||
|
|
.Nm
|
||
|
|
utility differs from its SVR4 counterpart in the following ways:
|
||
|
|
.Bl -bullet -compact
|
||
|
|
.It
|
||
|
|
If the
|
||
|
|
.Fl d
|
||
|
|
option is specified, it causes any
|
||
|
|
.Fl a ,
|
||
|
|
.Fl c
|
||
|
|
and
|
||
|
|
.Fl p
|
||
|
|
options present to be ignored.
|
||
|
|

||
|
|
.Fl a ,
