I am looking for an easy way to cut key-value pairs (where the key is unique and specified) from text, much like how
cut can be used to cut a specified column in a CSV file. The keys I'm looking for are not always in the same relative position in the line -- that is, using
cut followed by
sed won't do the trick, because they key I'm looking for is not always in the same
The text in question is indeed CSV, but it so happens that the values are key/value pairs, delimited with an
For example, I might parse a file with the following three lines:
Foo=1, Bar=2, Baz=3 Bar=4, Foo=2, Baz=3 Bar=42, Baz=42, Foo=3
And I would like to cut this text to yield the key/value pair for a specific key. If I was looking for
Foo, then my desired output would be:
Foo=1 Foo=2 Foo=3
Ideally I would like a command-line tool that has similar syntax as
cut, and can read both from stdin and from a file.
Is there such a tool?
