Hide the name of a process listed in the `ps` output

exec -a "/sbin/getty 38400 tty7" your_cmd -erase_all_files
exec -a $NAME $COMMAND $ARGS `your_cmd -erase_all_files` is the real process, but harmless-looking getty appears in the process table. Never actually had a need to do this, but interesting nonetheless... Tested in bash, dash. -a $NAME "pass NAME as the zeroth argument to COMMAND", i.e. customise the name of the process (as commonly seen with `ps`)
Sample Output
$ exec -a "/sbin/getty 38400 tty7" your_cmd -erase_all_files

$ ps -ef
[...]
user1       8765  2655  0 18:39 pts/7    00:00:00 /sbin/getty 38400 tty7
[...]

Does not seem to conceal the command argument in the ps output. The "r1" in the following case: # command exec -a "/sbin/getty 38400 tty7" /usr/sbin/lsof -r1 # ps output 00:00:01 /sbin/getty 38400 tty7 -r1
