I have a readline script. I want to use its output which by name is one line of a text file. how do I or even can I save this to a variable in a script file?
An alternative to backticks in bash is $(cmd). I generally use backticks myself, but our work servers use and older version of bash, and I came across something that didn't work with backticks, but did with the $().
n=`add $2 1`
then compare `sh readline $1 $2` and `sh readline $1 $n` is that where I might use $()?
readline is a head -nM and then a tail -n1 to get the Mth line. the file is a listing of files, no repeats. so this comparison is sort of like an end of file.
