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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
White space

Is there a way of deleting the spaces between data in a file?

Posted by admin (Graham Ellis), 30 June 2005
Best plan ... open the file for read and a new file for write. Read the original file line by line, use a regsub to strip out the spaces, and write the data back to the new file.

The line
regsub -all {[ \r\t\n]+} $inline "" outline
will remove all white spaces (space, tab, new line and carriage returns) from the string in the variable inline and save it to the variable outline
