One char options not used: F G J K P Q Y

|
|
Test if -0 works on filenames ending in '\n'
|
|
|
|
monitor to see which jobs are currently running

|
|
|
Accept signal INT instead of TERM to complete current running jobs but
|
|
do not start new jobs. Print out the number of jobs waiting to
|
|
complete on STDERR. Accept sig INT again to kill now. This seems to be
|
|
hard, as all foreground processes get the INT from the shell.
|
|
|
|
If there are nomore jobs (STDIN is closed) then make sure to
|
|
distribute the arguments evenly if running -X.
|
|
|
|
|
|
Reuse ssh connection (-M and -S) if not using own ssh command.

ssh -MST /tmp/ssh-%r@%h:%p-$SEED elvis
|
|
rsync --rsh="ssh -S /tmp/ssh-%r@%h:%p-$SEED" gitup elvis:/tmp/
|

ssh -S /tmp/ssh-%r@%h:%p-$SEED elvis hostname

Parallelize so this can be done:
|
|
mdm.screen find dir -execdir mdm-run cmd {} \;
|
|
Maybe:
|
|
find dir -execdir par$ --communication-file /tmp/comfile cmd {} \;
|
|
|
|
=head2 Comfile
|
|
|
|
This will put a lock on /tmp/comfile. The number of locks is the number of running commands.
|
|
If the number is smaller than -j then it will start a process in the background ( cmd & ),
|
|
otherwise wait.
|
|
|
|
par$ --wait /tmp/comfile will wait until no more locks on the file
|
|
|
|
=head2 mutex
|
|
|
|
mutex -n -l lockid -m max_locks [command]
|
|
mutex -u lockid
|
|
|
|
-l lockfile will lock using the lockid
|
|
-n nonblocking
|
|
-m maximal number of locks (default 1)
|
|
-u unlock
|
|
|
|
If command given works like: mutex -l lockfile -n number_of_locks ; command; mutex -u lockfile
