“grep” offset of ascii string from binary file

grep --byte-offset --only-matching --text foobar filename

The --byte-offset option prints the offset of each matching line.

The --only-matching option makes it print offset for each matching instance instead of each matching line.

The --text option makes grep treat the binary file as a text file.

You can shorten it to:

grep -oba foobar filename

It works in the GNU version of grep, which comes with linux by default.┬áIt won’t work in BSD grep (which comes with Mac by default).
