using bind to remove a file
file delete command:
http://www.tcl.tk/man/tcl8.4/TclCmd/file.htm#M12
:>
Code: Select all
file delete $file:>
im confused this is my proc
#delete the file process
proc del:file {nick user@host handle text} {
set delfile [lindex $text 1].ins
putserv "PRIVMSG $nick :[lindex $text 1] has been removed"
[file delete $delfile]
}
it works like it is but if I place the putserv command beneath the
[file delete $delfile]
the putserv command does not execute. above it, it works fine.
what is it in [file delete $delfile] that stops my process
if I had to execute something after this command how would I?
thanks so much

1st:
Don't use lindex like that... $text is a string, not a list (consider using split to convert it into a list).
2nd:
Don't enclose the file command with [] if you do not intend to make use of the return code. Currently, you are trying to execute the return code from the file delete operation as a new command.
The file delete command will always return an empty string, causing your script to try and execute "", which is not a valid command. This will generate an error, and script execution is terminated.
