For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
removing periods with a shell script

Posted by simulatonofjohn (simulatonofjohn), 13 April 2008
Does anyone out there know of a way for me to remove periods from a group of files without removing the period that delineates the extension.  I have had moderate success with removing periods, but cannot seem to do so without removing that danged last one.  If anyone can help, I would be very grateful.

Do you mean from the name of the file?  Renaming files to a pattern?  Which shell?

Posted by simulatonofjohn (simulatonofjohn), 13 April 2008
Sorry, I am using a Bash script to remove punctuation and spaces from the filename. for example, if a photo was named "John's Mother 7.4.2002.jpg"  the result would be "JohnsMother742002.jpg".

You will probably accuse me of cheating, but this works!

Code:
#!/bin/bash
perl -e 'foreach(glob("*")){$s=$_;s/(.*)\./\1\//;s/[^[:alnum:]\/]//g;s/\//./;rename($s,$_);}'
