I need to extract the highlighted part beginning with ES_
I tried using
curl <...> | sed '"progressId"\:"(ES_[A-Za-z0-9]{15})'
however it still stores the entire output in the environment variable.
This should work:
curl <...> | sed -E -n 's/.*(ES[^"]+).+/\1/p'
Explanation:
.* means 'any char 0 or more times'ES[^"]+ means 'ES followed by any char which is not " one or more times'.+ means 'any char 1 or more times'\1 means 'the first group', so what's inside ()p means 'print only matching lines'If you want to store it in a variable you can do it with backtick ` like this:
VAR="$(curl <...> | sed -E -n 's/.*(ES[^"]+).+/\1/p')"
