| 32 B<sea> - B<Shell Execution Archive> | |
| 33 | |
| 34 =head1 SYNOPSIS | |
| 35 | |
| 36 B<sea> | |
| 37 [B<-h>|B<--help>] | |
| 38 [B<-o>|B<--output> I<sea>] | |
| 39 I<script> | |
| 40 [I<file-or-dir> ...] | |
| 41 | |
| 42 =head1 DESCRIPTION | |
| 43 | |
| 44 The B<sea> utility allows you to wrap a control shell script (I<script>) | |
| 45 plus zero or more payload file or directories (I<file-or-dir>) into a | |
| 46 so-called I<Shell Execution Archive> (I<sea>), a sh(1) executable script | |
| 47 which temporarily auto-extracts its payload and pass-through execution | |
| 48 to the control script. | |
| 49 | |
| 50 =head1 OPTIONS AND ARGUMENTS | |

| 54 =item B<-h>|B<--help> | |
| 55 | |
| 56 Just shows a short usage information of the B<sea> utility. | |
| 57 | |
| 58 =item B<-o>|B<--output> I<sea> | |
| 59 | |
| 60 The output I<Shell Execution Archive> file. By default the output is | |
| 61 saved to a file with a basename derived from I<script> and with new | |
| 62 attached extension F<.sea>. | |
| 63 | |
| 64 =item I<script> | |
| 65 | |
| 66 The mandatory control script which is added to the payload and which | |
| 67 (after auto-extraction) is executed. It receives all command-line | |
| 68 arguments originally passed to the I<Shell Execution Archive>. | |
| 69 | |
| 70 =item I<file-or-dir> | |
| 71 | |
| 72 Optional number of files or directories which are added to the payload. | |

| 80 =head1 HISTORY | |
| 81 | |
| 82 The B<sea> command was implemented in April 2012 by I<Ralf S. Engelschall> | |
| 83 E<lt>rse@engelschall.comE<gt>. Its idea is based on the | |
| 84 OpenPKG shell packages (F<openpkg.src.sh>) and its implemenation was | |
| 85 triggered by the demand for self-contained OpenPKG software stack source | |
| 86 archives. | |
