I think the only things you will have to convert are the ESC strings
themselves (the ]00m can be left literal). This perl script will
convert all the ESC's back into their actual binary values (ascii 27):
====================
#!/usr/bin/perl
foreach (<>){
s/ESC/chr(27)/eg;
print;
}
====================
Just put it in a file named 'conv.pl' , make it executable, and run it like:
conv.pl < logfile > converted_logfile
or
conv.pl logfile > converted_logfile
The limitations of this script is that it will convert *any* literal
string of ESC to a non-pritable character (for example in
DESCRIPTION). This could be fixed by modifying the regular expression
if we knew more context (does ] ALWAYS follow ESC in the escape
sequences? Do they always consist of 5 characters? What letters can
they end in?)
For the most past, this should do the trick though.
