Shell: How to cut a single string with "Cut"?
You can use Here Strings in BASH:
cut -d' ' -f1 <<< "hello 12345 xyz"hello
There are several ways to do this in bash itself. If your string is already in a parameter (or you don't mind assigning it to one, you can use read:
str="hello 12345 xyz"read first rest <<< "$str"or parameter expansion:
echo "${str% *}"or regular expression matching:
[[ "hello 12345 xyz" =~ ([^ ]+)\ ]]echo "${BASH_REMATCH[1]}"
To get cut to act on a string instead of a file, you have to give it the string via STDIN. The most common way to do so is this:
$ echo 'hello 12345 xyz' | cut -f 1hello
