Operating Systems Linux Selecting substring (like SQL Server function) Post 302452602 by ProGrammar on Saturday 11th of September 2010 08:26:21 PM

lemme rephrase...

what keywords should I research to find more about the use/features/options of the ":#:#" convention??

e.g. does that feature have a name?!

You know variable expansion covers how the shell interprets variables, but if people don't know the term "expansion", they might query for the wrong things. You get my point...

I've read lots of documentation and have never come across that, I'm thoroughly familiar with sed, my awk knowledge needs to catch up though.

Dude, I really appreciate this technique. It'll be very helpful when extracting certain portions of uniformly-formatted strings and storing to variables.

So if you know of a particular name (keyword) for that string:#:# technique, I'd appreciate it.

When the -format option is not given, the search path used when looking for a file is inferred from the name given, by looking for a known extension. If no known extension is found, the search path for TeX source files is used. OPTIONS

See the info manual for a list of valid names, or use the -help option to print the list. -help Print help message and exit. -interactive Ask for additional filenames to look up. -mktex fmt enable mktexfmt generation. (fmt=pk/mf/tex/tfm) -mode string Set device name for $MAKETEX_MODE to string; no default. -must-exist Search the disk as well as ls-R if necessary. -no-mktex fmt disable mktexfmt generation. (fmt=pk/mf/tex/tfm) -path string Search in the path string. -progname string Set program name to string. -show-path name Output search path for file type name.
