Marrant

J’ai enfin pris le temps de lire l’article et il est vraiment drôle.

Il y a un point qui mérite un exemple à mon avis :

Don't depend on your command's name to determine its scope. Keep those decisions separate.

$ ln -s /usr/bin/pgrep pkill
$ ./pkill --version
pkill from procps-ng 3.3.16
$ ln -s /usr/bin/pkill foobar
$ ./foobar --version
foobar from procps-ng 3.3.16
$ ./foobar -h
Usage:
 foobar [options] <pattern>
Options:
 -d, --delimiter <string> specify output delimiter
 -l, --list-name list PID and process name
 -a, --list-full list PID and full command line
 -v, --inverse negates the matching
 -w, --lightweight list all TID
 -c, --count count of matching processes
 -f, --full use full process name to match
 -g, --pgroup <PGID,...> match listed process group IDs
 -G, --group <GID,...> match real group IDs
 -i, --ignore-case match case insensitively
 -n, --newest select most recently started
 -o, --oldest select least recently started
 -P, --parent <PPID,...> match only child processes of the given parent
 -s, --session <SID,...> match session IDs
 -t, --terminal <tty,...> match by controlling terminal
 -u, --euid <ID,...> match by effective IDs
 -U, --uid <ID,...> match by real IDs
 -x, --exact match exactly with the command name
 -F, --pidfile <file> read PIDs from file
 -L, --logpidfile fail if PID file is not locked
 -r, --runstates <state> match runstates [D,S,Z,...]
 --ns <PID> match the processes that belong to the same
 namespace as <pid>
 --nslist <ns,...> list which namespaces will be considered for
 the --ns option.
 Available namespaces: ipc, mnt, net, pid, user, uts
 -h, --help display this help and exit
 -V, --version output version information and exit
For more details see pgrep(1).
