General :: Getting Sub-string In A Variable

Jul 13, 2010

General :: Bash: Substitute Parameter In A Quoted String - Stored In Another Variable

Jan 31, 2010

(variable substitution?)
(parameter expansion?)
Code:
run_repeatedly()
{
NUM=0
while [ <irrelevant stuff here> ]
[Code]....

run_repeatedly "programX -o "./messy/path/output-$NUM.txt"" The echo inside the loop prints "...-$NUM.txt"; obviously I'm aiming to have bash substitute the iteration number so that I end up with many output files not 1.
