Journal Mmm coffee's Journal: A little bash help?
Learning bash scripting by writing a "dir" script that emulates the look and feel of Windows's dir command. I have a problem that I can't quite figure out. I want to make text (say in a variable $i) uppercase. So far I've made it work using a fuxx0red up sed command -
nameinupper=$(echo ${filename[$outputcount]} | sed -e 's/a/A/g' -e 's/b/B/g'\
-e 's/c/C/g' -e 's/d/D/g' -e 's/e/E/g' -e 's/f/F/g' -e 's/g/G/g' -e 's/h/H/g'\
-e 's/i/I/g' -e 's/j/J/g' -e 's/k/K/g' -e 's/l/L/g' -e 's/m/M/g' -e 's/n/N/g'\
-e 's/o/O/g' -e 's/p/P/g' -e 's/q/Q/g' -e 's/r/R/g' -e 's/s/S/g' -e 's/t/T/g'\
-e 's/u/U/g' -e 's/v/V/g' -e 's/w/W/g' -e 's/x/X/g' -e 's/y/Y/g' -e 's/z/Z/g');
I could care less that it's ugly. I do care that it really kills the speed of the script. Is there a better way to make text upper case in a bash script without having to write a C program that uses toupper()?
