Change chars(hex) in files with a script

Hi,

can anyone help me to write a script? I want to change all chars in a file with the hex "DC" to "9A".

Thanks a lot.

Try this:

sed -e 's/DC/9A/g' myfile > mychangedfile

jdfox

Oops, you did say hex characters. It should then actually be:

sed -e 's/\xDC/\x9A/g' myfile > mychangedfile

jdfox, which sed implementation are you using where that works? I've tried it with GNU sed and Solaris 8 sed, and neither of them did what was expected.

smilidon, I believe this should work for you:

nawk '{gsub("\xDC", "\x9A"); print}' file

If you don't have 'nawk' then try gawk/mawk/awk or whatever you have, as long as it supports the gsub() function.
