This command can be used many ways. One possible use is to strip pathnames and extensions off of filenames.

---

For stripping off extensions from filenames, use [file rootname] instead of [string trimright]!

---

Supposing you have a directory of .log files and you want to return the filename with out its' extension, try:

   foreach lfn [glob -directory ./Logs -nocomplain -- *.log] {
      lappend fn [string trimright [string trimleft $lfn ./Logs/] .log]
   }

[GG: This only works if you can be sure that the basename of your logfile doesn't end in any combination of l, o and g. for example:

   % set str "smeagol.log"
   % set newstr [string trimright $str ".log"]
   % set newstr
   smea

I like stripping leading and trailing whitespace and field delimiters with 'string trim' commands, but not filename manipulation.

---

   lappend fn [string trimright [string trimleft $lfn ./Logs/] .log]

is not a good idea. It will strip l, o and g from the end of the file name, similarly the front. The string trim_x commands remove any character from the set given as the last argument.
