Under Edit ->Preferences -> Advanced -> Config Editor set the following parameter

user_pref("mail.check_all_imap_folders_for_new", true);

And if you don't want the sending bar that pops up set the following parameter

user_pref("mailnews.show_send_progress", false);

Are you really bugged by the need to keep changing your browser proxy setting to access blocked sites ?

FoxyProxy is the answer to all your proxy woes.

If you are using a proxy proxy.com to access all sites running on port 7777 then do the following :

1. Add proxy.com as proxy
2. Then for that proxy add a pattern like http://*:7777
3. Select "use proxies based on pattern"

Bingo, now all http access to port 7777 will be routed through proxy.com.

If there is redirection involved, please add both the url patterns (the redirected to and redirected from) to that particular proxy.

Requirement : Obtain line no and first field (if it is a number) from the following datafile


31726108012^Abicyclepatrolpuyallup^A0^B
31726228012^Acommercialguardseattlesecurity^A0^B
31726230512^Aconstructionguardkentsecurity^A0^B
31726241512^Aeventfederalguardsecurityway^A0^B

^A indicates ctrl + A

perl -n -e '@line= split /^A/,$_ ; if (int($line[0]) != 0) { print "$. " . $line[0] ."\n" }' datafile

$. gives us the line no.
int(any non numeric value) will return 0.

To generate ctrl A use the following key combination ctrl + v + a. The output generated will be as follows :

5 31726228012
6 31726230512
7 31726241512
8 31726254012

Logfiles in older unix systems and monitoring systems just log the unix timestamp as the first field in the enteries. When we try to pull out data for a particular date, then it becomes tricky. The following code snippet will help pulling out data for a particular date quite easily

cat <logfile> | perl -lane '$_=$F[0]; s/\[//g ;s/\]//g; $date=`date -r $_` ; chomp($date); $out=$date . " " ; foreach(@F[1..scalar(@F)]) { chomp($_); $out=$out. $_." "; }; print $out'

After the perl snippet you can use commands like grep to filter out data based on date.

Some alternate way to do it :

cat file | perl -p -e 's/^\[(\d+)\] /localtime($1)/e;' //source philip


Code snippet just to pre append time to every line :

perl -p 'print time, " ";' //thanx philp
