gbch-cvlist - dump out GNUbatch variables to a shell script
gbch-cvlist [ -D dir ] [ -v n ] [ -e n ] [ -s ] [ -f ] var file outfile
gbch-cvlist converts GNUbatch variables held in the batch spool directory to an executable shell script which may be used to re-install them. This may be useful for backup purposes or for one stage in upgrade from one release of GNUbatch to another.
gbch-cvlist understands the format of the saved variable file for versions of Xi-Batch going back to release 4, and when presented with a saved file, will attempt to work out from the format which release it relates to.
In addition to options, two arguments are always supplied to gbch-cvlist.
This is the file containing the attributes of the variables,
btsched_vfile in the batch spool directory, by default
/usr/spool/batch, or as relocated by re-specifying SPOOLDIR
.
This file is created by gbch-cvlist to contain the executable shell script, containing gbch-var(1) commands, which may be used to recreate the variables.
Specifies the source directory for the variables and var file if
not the current directory. It can be specified as $SPOOLDIR
or
${SPOOLDIR-/var/spool/gnubatch}
etc and the environment and/or
/etc/gnubatch.conf will be interrogated to interpolate the value
of the environment variable given.
If you use this, don't forget to put single quotes around it thus:
gbch-cvlist -D '${SPOOLDIR-/var/spool/gnubatch}' ...
otherwise the shell will try to interpret the $
construct and not
gbch-cvlist.
Tolerate n errors of the kinds denoted by the other options before giving up trying to convert the file.
Ignore format errors in the saved variable file, skip over invalid entries up to the limit given by the -e option.
Ignore file size errors in the saved variable file (up to the number of total errors given by the -e option).
Tell gbch-cvlist that the variable file is for release number of Xi-Batch, where number is 4 to 6.
This may be necessary where the variable file is corrupted and gbch-cvlist cannot guess what is meant.
gbch-ciconv(8), gbch-cjlist(8), gbch-uconv(8).
