I want to remove non-ascii chars from some file. I have already tried these many regexs.
sed -e 's/[\d00-\d128]//g' # not working
cat /bin/mkdir | sed -e 's/[\x00-\x7F]//g' >/tmp/aa
but this file contains some non-ascii chars.
[root@asssdsada ~]$ hexdump /tmp/aa |more

This doesn't seem to work with sed
. Perhaps tr
will do?
tr -d '\200-\377'
Or with the complement:
tr -cd '\000-\177'
