I'm trying to extract a certain (the fourth) field from the column-based, 'space'-adjusted text stream. I'm trying to use the cut
command in the following manner:
cat text.txt | cut -d " " -f 4
Unfortunately, cut
doesn't treat several spaces as one delimiter. I could have piped through awk
awk '{ printf $4; }'
or sed
sed -E "s/[[:space:]]+/ /g"
to collapse the spaces, but I'd like to know if there any way to deal with cut
and several delimiters natively?
Try:
tr -s ' ' <text.txt | cut -d ' ' -f4
From the tr
man page:
-s, --squeeze-repeats replace each input sequence of a repeated character that is listed in SET1 with a single occurrence of that character
