    Switching betwen two directories in Bash 

    The pushd command remembers the last pushd’ed from directory
    #cd /
    #pushd /home
    #pwd
    /home
    #pushd
    #pwd
    /

    But quicker is “~-” which will simply take you back to the last working directory
    #cd /
    #cd /home
    #pwd
    /home
    #cd ~-
    #pwd
    /

    giving permission to read a specific file using sudo:
    visudo
        #Support Staff
        Cmnd_Alias = LOGS = /bin/cat /var/log/squid/access.log, /bin/zcat /var/log/squid/access.log.[0-9].gz
        %logaccess ALL (all) NOPASSWD: LOGS

    This gives access to the Squid Logs to anyone in the logaccess group.
    (sudo zcat /var/log/squid/access.log.1.gz) | grep "microsoft.com"

    Proxy.Pac files can be tricky. The way to identify the client is:
    myIPAddress()
    But this fails occassionally, reporting the LocalHost address instead, especially in Linux.
    Additionally, on Windows 7 multiple enabled interfaces can lead to the wrong one reporting back.
    There is no fix but DISABLING the inappropriate interfaces and re-enabling them can work.
