When I open a file in vi, I see the following characters:
\302\240
Can someone explain what these characters mean. Is it ASCII format? I need to trim those characters from a file.
I am doing the following:
tr -d '\302\240'

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
