At the end of a long computation, I need to show all the results (several files) in a given folder.
On Windows I can do something like this
exec {*}[auto_execok start] c:/tmp
or
exec cmd /C start c:/tmp

What are the equivalent commands for Linux and Mac ?

OS X: open

These are the command line tools for running some arbitrary "thing",
from within Tcl you need to prepend with exec, of course.

I have this proc in my Tcl swiss-knife:

proc StartFileBrowser { dir } {
if { $::tcl_platform(platform) eq "windows" } {
set browserProg "explorer"
} elseif { $::tcl_platform(os) eq "Linux" } {
set browserProg "konqueror"
} elseif { $::tcl_platform(os) eq "Darwin" } {
set browserProg "open"
} elseif { $::tcl_platform(os) eq "SunOS" } {
set browserProg "filemgr -d"
} elseif { [string match "IRIX*" $::tcl_platform(os)] } {
set browserProg "fm"
} else {
set browserProg "xterm -e ls"
}
if { [file isdirectory $dir] } {
eval exec $browserProg [list [file nativename $dir]] &
}
}

Just out of curiosity: on which platform/universe is
exec xterm -e ls &
useful?

On my Linux system an xterm appears and disappears instantly -
too short for my human eyes to grok... :-)

And as an FYI, it would fail on my Slackware systems as there is no
"konqueror" (I purposefully do not install KDE).

The -e option tells xterm to execute the command, and when the command
is done, xterm exits. If you want it to hang around, then the command
has to wait for user interaction in some way:

xterm -e bash -c 'ls ; read -p "Press Return" junk'

Similar to "start" on Windows and "open" on Darwin, it can "run" all
kinds of "things". Folder paths open a file manager window, URLs open a
browser, files open the associated program, so for instance, you could
play a soundfile with

xdg-open some.mp3
or open a text processor with
xdg-open some-word.docx

@Christian
Thank you for the Linux suggestion. I only added "2>/dev/null" in order to discard some diagnostic message

# open folder /tmp
exec xdg-open /tmp 2>/dev/null

Thanks again
