| Permit regular expressions in \fIsymbolname\fRs used in other command |

| square brackets ([]) operators can be used anywhere in the symbol |
| name. If the first character of the symbol name is the exclamation |
| point (!) then the sense of the switch is reversed for that symbol. |
| For example: |
| .Sp |
| .Vb 1 |
| \& \-w \-K !foo \-K fo* |
| .Ve |
| .Sp |
| would cause strip to only keep symbols that start with the letters |

| (These usually start with \fBL\fR or \fB.\fR.) |
| .IP "\fB\-\-keep\-file\-symbols\fR" 4 |
| .IX Item "--keep-file-symbols" |
| When stripping a file, perhaps with \fB\-\-strip\-debug\fR or |
| \&\fB\-\-strip\-unneeded\fR, retain any symbols specifying source file names, |
| which would otherwise get stripped. |
| .IP "\fB\-\-only\-keep\-debug\fR" 4 |
| .IX Item "--only-keep-debug" |
| Strip a file, removing contents of any sections that would not be |
| stripped by \fB\-\-strip\-debug\fR and leaving the debugging sections |
| intact. In \s-1ELF\s0 files, this preserves all note sections in the output. |
| .Sp |
| The intention is that this option will be used in conjunction with |
| \&\fB\-\-add\-gnu\-debuglink\fR to create a two part executable. One a |
| stripped binary which will occupy less space in \s-1RAM\s0 and in a |
| distribution and the second a debugging information file which is only |
| needed if debugging abilities are required. The suggested procedure |
| to create these files is as follows: |

| i.e., the file pointed to by the \fB\-\-add\-gnu\-debuglink\fR can be the |

| .Sp |
| Note\-\-\-this switch is only intended for use on fully linked files. It |
| does not make sense to use it on object files where the debugging |
| information may be incomplete. Besides the gnu_debuglink feature |
