| # xebcdic.sh fileName [--all-ascii-content] [--f=pattern ... ] |
| # |
| # This shell script decompresses an archive containing an apache source tree |
| # and then extracts the source files from the archive. The source files are |
| # translated from ASCII to EBCDIC as they are extracted from the archive. |
| # Once all the files have been extracted and translated, the binary files are |
| # re-extracted to undo the ASCII to EBCDIC translation on those files. Once |
| # this script is done, the extracted tree can be used on an EBCDIC based |
| # system. |
| # |
| # Input: fileName -- fileName has one of the following formats: |
| # apache-version_timeStamp.tar.gz or |
| # apache-version_timeStamp.tar.Z or |
| # apache-version.tar.gz or |
| # apache-version.tar.Z or |
| # apache_version.tar.gz or |
| # apache_version.tar.Z |
| # |
| # --f=pattern -- specifies that all files which match the pattern |
| # are to be re-extracted without ascii to ebcdic |
| # translation being applied. pattern is a file name |
| # specification that may contain path names and |
| # the wildcard character. All paths are assumed to |
| # be under the apache source tree top. Binary files |
| # are always re-extracted without ascii to ebcdic |
| # translation regardless of whether any pattern is |
| # specified or not. Multiple patterns may be specified |
| # by repeating this option. |
| # |
| # |
| # --all-ascii-content -- specifies that all the text content shipped |
| # with the apache tree should be stored in |
| # ascii on the OS/390 system. This re-extracts |
| # all the *.htm* files in the htdocs directory |
| # of the apache tree without doing the ascii |
| # to ebcdic translation. In addition to the |
| # *.htm* files, file htdocs/manual/LICENSE and |
| # file htdocs/manual/misc/HTTP_Features.tsv |
| # are also stored in ascii. If this option |
| # is specified, directives AddType and |
| # DefaultType need to be used to correctly |
| # serve the pages without trying to first |
| # translate from ebcdic to ascii. See |
| # apache-tree-top/src/README.EBCDIC. |
| # |
| # Example Invocations: |
| # |
| # ./xebcdic.sh apache_1.3.9.tar.gz: Runs gunzip, runs pax and |
| # extracts everything translating it to ebcdic, and re-extracts |
| # all gif files in the htdocs and icons directories without |
| # applying ascii to ebcdic translation. |
| # |
| # ./xebcdic.sh apache_1.3.9.tar.gz --f=*.htm* --f=htdocs/*.tsv: |
| # Runs gunzip, runs pax and extracts everything translating it to |
| # ebcdic, re-extracts all gif files without ascii to ebcdic |
| # translation, and re-extracts all the *.htm* files in the apache |
| # source tree and all *.tsv files in the htdocs directory of the |
| # apache source tree without ascii to ebcdic translation. |
| # |
| # ./xebcdic.sh apache_1.3.9.tar.gz --all-ascii-content: Runs gunzip, |
| # runs pax and extracts everything translating it to ebcdic, |
| # re-extracts all gif files without ascii to ebcdic translation, |
| # and re-extracts all the *.htm* files in the htdocs directory |
| # as well as htdocs/manual/LICENSE and |
| # htdocs/manual/misc/HTTP_Features.tsv without ascii to ebcdic |
| # translation. |
| # |
| # Output: fileName.tar.gz is replaced with fileName.tar and the apache |
| # source tree is extracted into a directory named apache-version or |
| # apache_version. All files except binary files and any files |
| # specified through the options are translated from ascii to |
| # ebcdic. |
| # |
| # Assumptions: The path to gunzip, uncompress and pax is defined and |
| # from where this script is invoked. |
