printing current line number - The Tcl programming language

Training, Open Source computer languages

Perl • PHP • Python • MySQL • Apache / Tomcat • Tcl • Ruby • Java • C and C++ • Linux • CSS

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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

printing current line number

Posted by arvindpal (arvindpal), 28 September 2006

How do I puts current line number?
I could find 'info script' to get the script name. I could not find command to get the line number.

Posted by admin (Graham Ellis), 28 September 2006

info cmdcount

will tell you the number of commands you've interpretted, but there's nothing that I know of to tell you the line number. That's quite logical, as proc commands store a procedure and the original file numbering is not retained at that point.

Thanks for your reply.

hmm.. In that case how does $LINENO work fine for shell script?

Posted by admin (Graham Ellis), 29 September 2006

Because Shell script is a different language that keeps track of which line it's at. There's a different "balance" between the languages - shell is a scripting tool in which you can define functions, but Tcl is a full procedure based language where named blocks of code that are stored are inherrently much more important.
