I'm using a sed command in a bash script from variable expansion, so I
can use it like this:
$CMD file
The command is the following:
sed -e 's/\(\([^|]*|\)\{22\}[^|]*\)|.*/\1/'
It makes sure that any trailing characters [beginning with |] beyond the
initial 23 pipe-delimited columns will be stripped off, and it does work
outside of this script that I'm writing.
However, I can't get the command to work. Per the bash man page, ', ",
and \ need to be escaped (for Quote replacement), so I've tried this:
CMD="sed -e \'s/\\(\\([^|]*|\\)\\{22\\}[^|]*\\)|.*/\\1/\'"
also this:
CMD="sed -e 's/\(\([^|]*|\)\{22\}[^|]*\)|.*/\1/'"
and several other variations.
Any suggestions for getting this to work using variable substitution?
