Ah yes. I totally missed your point, sorry! Indeed:

  $ mksh -c 'sleep 1 & fg'   # ok.
  mksh: fg: job control not enabled
  $ mksh -m -c 'sleep 1 & fg'# not ok. 
  mksh: fg: job control not enabled

Curiously, It works as expected with the -i option (which implies
the job monitor):

  $ mksh -i -c 'fg'
  mksh: fg: %%: no such job

As if '-m' was just ignored.

You're also right for the xclock case; bash works as expected.

Sorry again,
Seb.

[BUG] New alias POSIX restriction breaks the hash built-in

2017-04-17 Thread Seb 
Hello,

It seems the R55 new alias definition policy prevents some
commands from being find in the PATH:

 $ echo $PATH
  /usr/local/bin:/usr/bin:/bin
 $ ls /usr/bin/python*
  /usr/bin/python /usr/bin/python2-config
  /usr/bin/python-config  /usr/bin/python2.7
  /usr/bin/python2/usr/bin/python2.7-config
 $ hash python; echo $?
  0
 $ hash python2; echo $?
  0
 $ hash python2.7; echo $?
  mksh: alias: python2.7: invalid alias name
  1

Even if it seems the dot is in the POSIX Portable Character Set
and should hence be allowed, I think an illegaly defined alias
should however not stop further searching.

Take care!
Seb.

My bad. I saw "launchpad", I thought "ubuntu", sorry. Coudn't it
help if you were running it through another shell? If [b]ash
properly reset the tty the problem would then be in mksh rather
than in a weird behaving of mpg123, wouldn't it?

Take care,
Seb.

I can't reproduce it, mksh R54 with mpg123 1.23.4 work well.
Have you tried to switch the output module with the '-o' option?
The default is likely to be pulseaudio, maybe mpg123 sometimes
struggles to deal with it. That's just an idea, of course, but I
would try alsa for a while. :)

Take care,

Better: it depends from where you call it. When it's exclusively
interactively from a terminal, I personaly make an alias to not
encumber my PATH (more).

Faster: don't bother, you can't however humanly notice it.

(BTW, I think you might shrink it a bit:

  netstat -lantp | grep -i stab | awk -F/ '{print $2 $3}' | sort -u

or, if you want to save the grep process:

  netstat -lantp | awk -F/ '/[sS][tT][aA][bB]/{print $2 $3}' | sort -u
)

My 2 cents.

 I think this must be … = $y to be fair. But that was not the
 problem.

Actually, I should have used a constant in the second parts in all the
tests, it would have been more accurate.

 And here are the results you get running it with different shells:
 
 tg@blau:~ $ mksh debug.sh a b c
 3
 2
 1
 tg@blau:~ $ mksh -c 'print $KSH_VERSION'
 @(#)MIRBSD KSH R48 2013/11/17
 
 Fixed in CVS HEAD now.

I wanted to test, but what I fetch with cvs by following the
instructions from the mksh's web page does not compile. This is the
only thing I get:

 In file included from lalloc.c:21:0:
 sh.h:671:24: fatal error: sh_flags.gen: No such file or directory
 compilation terminated

Chair/keyboard interface problem (I'm not familiar at all with
cvs) or not? :)

Take care,
Seb.
