For anyone who has followed my other posts, huge advantage to getting scripts and tools running smooth and as intended on TinyPaw, Xiaopan, TCL is updated Grep with perl regular expressions built in. I am sure you've seen "grep: not compiled with -P support --disable-perl-regexp" in your terminal. These extensions are the latest build for grep, pcregrep and pcre2grep, compiled in TinyPaw on the TCL 8.2.x core. Enjoy ~ Installation notes: All included extensions can be saved in your "*/tce/optional/" directory and overwrite any existing previous installed extension - most likely "pcre.tcz and grep.tcz" Make sure grep, pcre and pcre2 are added to your "onboot.lst" file located in your "*/tce/" directory and make sure to add an extra empty space "white line" after the last added line. Reboot your release of Xiaopan / TinyPaw / TCL *As stated above, compiled & tested on Core 8.2.1*
