To open a random (already existing) file, I'd suggest you first get a list of files using glob, get the lenght of the list using llength, and generate a random number between 0 and length-1 (using rand) to be used with lindex to retrieve the randomly selected file.

Code:

set files [glob "mydir/*"]set file [lindex $files [rand [llength $files]]]

Once you have the filename, perform your file operations just as you would with any other file.

Alright, I'm sorry I didn't check there :C I'll try what the topic there says and I'm pretty sure it'll work. One thing though, how can I pick a random file from a list of files in a directory? Is that possible? Thanks again in advance :3

Hi there, all.
I'm trying to go for a bit more dynamic scripts which are managing files and withdraws information from them. Although, I just can't seem to really understand how file managing works in Tcl. If anyone would be willing to help, it'd be great! What I need to know is:

When do I need to open/close files? Let's say I want a file to be accessed whenever the bind is activated.
How do I tell it to access specific lines in a file?
How do I write one line to the last line in the file?

Thanks in advance!
