"Non-ascii character detection (perl or grep)"

Post #302107579 by mschwage on Monday 19th of February 2007 09:31:16 AM

Try this...

tr -d "\000-\011\013-\177" < txtfile

...where txtfile is the file you want to scan for non-ascii chars.

This will send txtfile to stdout, but along the way delete every ascii char except newline.

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
