Bash completion error — quote_readline.

2010-04-11 1 min read Bash

There is a problem with bash completion with quote_readline that causes the completion to fail. The problem is fixed in the bash completion package but there are still some other programs which are using the problematic code. Here is a way to find and resolve it.

First find the problematic program, most likely the recent one after which you started having the problems. Once that is found, find the file containing the definition of the function ”_filedirs()”. Now, delete this file and create a symbolic link to the bash_completion file in the /etc directory. If this file is not present then you need to install the bashcompletion package.

PuTTY export client display on login for opening X application and terminal.

2010-04-11 1 min read Bash Linux

export DISPLAY=$(echo $SSH_CLIENT |awk '{print $1”:0.0”}’)

Explanation:

SSH_CLIENT contains the IP and the port of the client machine. So we need to export (Client IP):0.0 for the display on the client machine. If the above is put in .bashrc or .bash_profile or .profile, then the DISPLAY variable will be set based on the client machine.

log analysis with perl and wireshark decode.

Here is something that I had to do in couple of hours to check the logs. The problem was the log file was printing the Received and Sent message in the hex format. I had to verify if the messages were correct. So here is how to do it.

open(FP, ”<$ARGV[0]”)|| die ”File $ARGV[0] does not exist”;
while ($line = )
{

if ($line =~ /(Received :)|(Sending :)/)

{

@words = split(/\|/, $words[4]);
$received = $words[1];
