What is your the most original command line trick/command you've come up with?

Just wanted to share some commands. See what other people have come up with.

I came up with this, to capture CDP packets:

Code:

tcpdump -nn -i eth1 -s 1500 -c 1 'ether[20:2] == 0x2000'

and I used this to change some HEX character to regular character:

Code:

find . -name "*.html" | xargs perl -pi -e 's|\xOLDHEXNUMBER|NEWTEXT|g'

List the last 50 RPM's installed in dated order:

Code:

rpm -qa --queryformat '%{installtime} (%{installtime:date}) %{name}\n' | sort -n | tail -50

This fixes file names:

Code:

for i in *
do
  mv "$i" $(echo "$i" | tr [:upper:] [:lower:] | tr [:blank:] _ | sed 's|[^-._a-z0-9]||g')
done

changes upper to lower case, changes white space to _, and finally removes any character except those in the brackets.

There are many commands here:

A function to run the Juniper Network connect client with user/pass and certificate.

Code:

NCremote() {
        cd /home/user/.juniper_networks/network_connect;
        echo "Signing into remote.google.com"
        echo "Rememeber to escape your password!"
        read -p "Username: " user
        read -p "Password: " pass
        java -jar NC.jar -h 4.4.4.4 -u $user -p $pass -f ../remote.google.com.cert -r "Google Remote Access" &
        cd ;}
