Description
powershell()
opens a new session of the MS Windows
powershell.exe command interpreter, sends command
to it, lets it processing command
instructions, receives as text the
output
and possible error message yielded by the processing,
and closes the interpreter session.
The starting current working directory and environment variables of the powershell.exe session are set as described for host().
If an instruction in command
generates an error, the error message
is caught and returned in output
. Nothing is directly displayed
neither in the Scilab console nor in the consolebox.
The effects of valid instructions processed before the erroneous one remain actual
(for instance, deleted files). However, their valid output is canceled and not
returned in output . |
Any path included in the command must be single-quoted. |
Examples
Current directory:
r = powershell("pwd"); r(4) // Directory content path = TMPDIR + "\répertoire test"; mkdir(path); mputl("Test of listing", path+"\test.txt"); [r,ok] = powershell("ls ''"+path+"''"); ok // single quotes ' needed rmdir(path, "s");
Handling of environment variables, date:
setenv TEST ABCD; powershell("$env:TEST") // Current date: [r,ok] = powershell("get-Date -format ""yyyy-MM-dd HH:mm"""); ok // => error [r,ok] = powershell("get-Date -format ''yyyy-MM-dd HH:mm''")
--> setenv TEST ABCD; --> powershell("$env:TEST") ans = ABCD --> // Current date: --> [r,ok] = powershell("get-Date -format ""yyyy-MM-dd HH:mm"""); ok ok = F --> [r,ok] = powershell("get-Date -format ''yyyy-MM-dd HH:mm''") ok = T r = 2018-04-30 07:12
Multiple instructions separated with ";":
powershell("echo $env:USERNAME'' uses powershell in Scilab'' ; Get-Date")
