Name

unix_g — shell (sh) command execution, output redirected to a variable

Calling Sequence

rep=unix_g(cmd)
[rep,stat]=unix_g(cmd)
[rep,stat,stderr]=unix_g(cmd)

Parameters

cmd

a character string

rep

a column vector of character strings (standard output)

stat

a integer, the error status. stat=0 if no error occured

err

a column vector of character strings (standard error)

Description

Sends a string cmd to Unix for execution by the sh shell. The standard output is redirected to scilab variable rep. The standard error is redirected to scilab variable err or displays if you had only 2 ouput arguments. Unix execution errors are trapped; *NOTE* that only the last shell command error is reported when a list of command separated by ";" is sent: this is not recommended.

Examples


function d=DIR(path)
  path=pathconvert(path,%t,%t)
  if MSDOS then
    d=unix_g('dir '+path)
  else
    d=unix_g('ls '+path)
  end
endfunction

DIR('SCI/etc')
