Finding funny charaters in a string - UNIX for Dummies Questions & Answers

ahjaeasedqa · #1 04-01-2007

Hi,

I have got a little problem where some of the files I created had some funny characters e.g space ,"^M" etc inserted in the full file name and which caused our backup script to skip those files.
Is it possible to find out if there are any funny charaters in a string ?

Thanks,

Code:

cat -vet <filename>

This will display all the control characters. ^ and $ represents the start and end of Line.

Mona,

Thanks for that and also could you please advise code in finding characters other than ASCII from a string e.g between chr(49) and chr(122).

Thanks

Try this

Code:

 egrep '[^]0-9a-zA-Z:;<>=\?@\[\\\^\_`]' <filename>

Mona,

Thanks for that. Could we include "/" as legitmate part of the string, as I am using full path name for the files.

Best regards
