Searching for 'wild' ascii charaters

[lvennard]

i have a log file that continues to get wierd ascii characters in it. The log file reader stops cold when it encounters them. Ive written a script that removes most of the problem areas but i am unable to remove ?binary? code from the log file since i cannot match it.

here is an example of a line i want removed
LN)ô§I@Maè³qÊX]RÌS<aúARï2SÚSf@\ZWSN²D>Za©'Á7ª ]ÌWXp@YèÁ2%ìd¢SMPPvF [&quot;M

the log is a web proxing log, so i imagine some sites are using binary encoding.

is there a regexp that will do this for me?
maybe something like &quot;> 126&quot; or something?

Is the binary data always on a separate line? If so, you might be able to use the following:

if ($Line =~ m/^\s*\w/) {
print &quot;ascii - $Line \n&quot;;
} else {
print &quot;binary - ignore \n&quot;;
}

Note that this handles a line w/ or w/o spaces starting with word character. Thus lines that start with a punctuation mark will be missed.

Another option is to using the &quot;ord&quot; function to get the ascii value of the first character.

unfortunatly no, it doesnt start on its own line.

&quot;date&quot;,&quot;time&quot;,&quot;user&quot;,&quot;website&quot;
&quot;date&quot;,&quot;time&quot;,&quot;user&quot;,&quot;website&quot;

in that format

the binary code is at the end of a link

here is any &quot;easy&quot; example.

You can use hex values in a regex, and you can make a character class with a range, so a regex like this

/[\x032-\x126]/

should match any &quot;normal&quot; character.
