2015-11-26Split do_ps() into get_ps() and show_ps() as a start on implementing --sort.Rob Landley
Change readfileat() to pass back length of read.
2015-11-09Cleanup pass: inline find_tty_name(), bounds check fscanf(), use libcRob Landley
functions to read major()/minor(), fix printf format warnings in error msg.
2015-11-09Make ps try harder to find a name for a tty.Elliott Hughes
2015-11-09On Android, ps' default output should match toolbox.Elliott Hughes
2015-11-09Add ps -n.Elliott Hughes
Both Android and GNU interpret -n to mean "show numeric users and groups", despite what POSIX says.
2015-11-09Add ps -o CMDLINE.Elliott Hughes
This is equivalent to Android's historical "NAME" column, showing the first element of /proc/pid/cmdline.
2015-11-02Add -P as short option for --ppid.Rob Landley
(The help infrastructure can collate and alphebetize short options, long options haven't got a standardized help text format. Not a hard requirement to have a short opt, but it's nice.)
2015-11-02Fix the ps -o CMD vs COMM distinction.Elliott Hughes
"comm" is the command name without arguments, and "cmd" the command line including arguments. Confusingly, "command" is a synonym for the *latter*, not the former. This implementation of "comm" matches the GNU ps behavior where the names are truncated, but Android historically used the full name from /proc/pid/cmdline instead, so this patch isn't sufficient to let us match the Android behavior.
2015-11-02Make ps -o error reporting intelligible.Elliott Hughes
I actually thought ps was segfaulting, and it wasn't until I was in gdb that I even noticed there was an error message at all, and even then I had to read the source to work out what it was trying to tell me. Before: $ ps -o user,pid,ppid,vsize,rss,nice,wchan,addr,unknown,stat,cmd ps: -o 'user,pid,ppid,vsize,rss,nice,wchan,addr,unknown,stat,cmd'@41 USER PID PPID VSZ RSS NI WCHAN ADDR$ After: $ ps -o user,pid,ppid,vsize,rss,nice,wchan,addr,unknown,stat,cmd ps: bad -o field 'user,pid,ppid,vsize,rss,nice,wchan,addr,unknown,stat,cmd' ^
2015-11-02Add ps -Z.Elliott Hughes
As with ls, it doesn't seem like -Z should be guarded behind LSM availability. On a non-SELinux system, the label is always "unconfined".
2015-11-02Add ps --ppid.Elliott Hughes
Used by Android.
2015-10-28Promote ps to posix.Rob Landley
