| Will Cardwell 2005-01-29, 3:57 pm |
| I'm looking for unwanted occurrences of hex A0 in each text file of a
certain file spec. I'm using SunOS Unix.
To test, I have tried:
egrep /\x41/ foobar and similar to try to reproduce:
grep A foobar
as well as similar with awk. I tried different quoting etc. but can't get it
to work.
Can anyone help?
Thanks so much,
Will Cardwell

od -x foobar | grep 'a0'

/usr/dt/bin/dtksh -c '
find . -type f -exec /usr/xpg4/bin/grep -q $'\xa0' \; -print'
Should output a list of text files containing the character
0xa0.

Sorry, I forgot to escape the inner quotes.
/usr/dt/bin/dtksh -c "
find . -type f -exec /usr/xpg4/bin/grep -q \$'\xa0' \; -print"

/usr/dt/bin/dtksh -c "find . -type f -exec /usr/xpg4/bin/grep -q \$'\xa0' {}
\; -print"
worked fine. ( Note {})
Thanks so much! I learned a lot finding the {} bug.
Best,
Will

Thanks! This worked fine but of course doesn't give file name and shows only
the hex. Nice amd simple.
Regards,
Will.

That was left as an exercise for the reader :-)
You already know the 'find' soultion, but here is the answer using 'od':
for i in foobar.*; do
od -x $i | grep 'a0' > /dev/null && echo $i
done

That will do it and I love it! I had not seen "od" before and looked it up
in man. Thanks again!
