I'm trying to use the Unix "sed" command form within a tcl file, like this: (to change multiple spaces to one space)
exec /bin/sed 's/ +/ /g' $file
I also tried exec /bin/sed 's/ \+/ /g' $file
(an extra backslash)
none of the version work, and I get the error
/bin/sed: -e expression #1, char 1: Unknown command: `''
The command works fine when run from a linux terminal
What am I doing wrong?
