Backup of txt file

You can simply use the "[file copy]" command provided with Tcl.

It's far quicker, and it doesn't given any of the hastle assosiated with {}'s in badly handled strings.

No, because then there would be lots of {}

But I tried putting all data into a string.... but that does not keep the newlines....

So maybe put it all into an array and load the lines into the new file?

so my question is...

array set x {}
how do I just add an element to x...?

u could just put the whole list into the file as it is... if u want to apply each element to the list :

Code:

foreach l $somelist {  puts $file $l}

this should do the trick

I think this:

Code:

set op [open $thefile r]set fs [read $op]

should put everything in the file into the $fs var

if not...

Code:

while {![eof $file]} {  set f "[gets $file]"  lappend somelist $f}

then this should read every line of the file and put them into $somelist

open the txt file and read it into a variable/list, then open a new file (the bak file) and put the variable in there.... [open $somefile a+] <--- that should make a new file if it does not already exists.... u might wanna check if the file exists

Hello, I want to make a backup of a file called words.txt to words.bak

So I was wondering how to do this... perhaps there is a copy function or something?
