get executing script name

[need4weed]

hi, i'd like to find out the executing scripts name. batch uses %0, python uses argv[0], php uses __FILE__ .... ect. what is tcl's way?

thanks! (i tried google)

Here is an example:

cmdargs.tcl

[COLOR=#0000ff]# command line arguments[/color]
[COLOR=#804040][b]set[/b][/color] script_name [COLOR=#008080]$argv0[/color]
[COLOR=#804040][b]set[/b][/color] cmd_arg01 [[COLOR=#804040][b]lindex[/b][/color] [COLOR=#008080]$argv[/color] [COLOR=#ff00ff]0[/color]]
[COLOR=#804040][b]set[/b][/color] cmd_arg02 [[COLOR=#804040][b]lindex[/b][/color] [COLOR=#008080]$argv[/color] [COLOR=#ff00ff]1[/color]]
[COLOR=#804040][b]puts[/b][/color] [COLOR=#ff00ff]"script_name = '$script_name'"[/color]
[COLOR=#804040][b]puts[/b][/color] [COLOR=#ff00ff]"cmd_arg01   = '$cmd_arg01'"[/color]
[COLOR=#804040][b]puts[/b][/color] [COLOR=#ff00ff]"cmd_arg02   = '$cmd_arg02'"[/color]

Output:

c:\Work>tclsh85 cmdargs.tcl foo bar
script_name = 'cmdargs.tcl'
cmd_arg01   = 'foo'
cmd_arg02   = 'bar'

Hi

Just two minor notes :

batch uses %0, python uses argv[0], php uses __FILE__ .... ect.

Wrong. In PHP you should also use the $argv predefined reserved variable, not the __FILE__ magic constant.

(i tried google)

Next time try the Tcl documentation too. It has the answer at tclvars.
