the problem is not the brackets, even this test code doesn't work when called from tcl:
Code:
exec awk -f alfa.awk -v was='test' bans-#test.txt > bans-#test-tmp.txt

Just curious, what does your awk script try to accomplish and why could it not be done in native tcl code?

Tcl Built-In Commands - exec manual page

If an arg (or pair of args) has one of the forms described below then it is used by exec to control the flow of input and output among the subbprocess(es). Such arguments will not be passed to the subprocess(es). In forms such as ``< fileName'' fileName may either be in a separate argument from ``<'' or in the same argument with no intervening space (i.e. ``

> fileName
Standard output from the last command is redirected to the file named fileName, overwriting its previous contents.

my guess is that space between the redirection character and output file name is not being interpreted as in shell

try without it, i.e. >bans-$chan-tmp.txt

Hi,
I'd like to call awk from a tcl script, but for some reason it doesn't work. No error message returned.

In my tcl I have this line to call the script:

Code:

exec awk -f alfa.awk -v was='{tr}{td}$mask' bans-$chan.txt > bans-$chan-tmp.txt

All parameters are send to the script correctly and the awk command works fine like this when called from bash.
Changing the script to point to an invalid .awk file makes it throw an error, so it seems awk is actually run. It just doesn't do what it's supposed to do when called from tcl.

Anyone got an idea what I got wrong?
