This will affect all users - The user environment setup scripts have been changed to include some common aliases that may be useful to users. alias ll='ls -alF' alias la='ls -A' alias l='ls -CF' alias target="cd /opt/rtcds/lho/h1/target/" alias t="cd /opt/rtcds/lho/h1/target" alias chans="cd /opt/rtcds/lho/h1/chans" alias h1="cd /opt/rtcds/lho/h1" alias userapps="cd /opt/rtcds/userapps/release" alias latest="ls -alt|head" alias scripts='cd /ligo/lho/scripts' alias data='cd /ligo/lho/h1/data' alias medmdir='cd /opt/rtcds/lho/h1/medm' (there's more than these...) If an individual user wishes to redefine one of these aliases, they can do so by editing the ".bashrc" file in their home directory to include a different alias command AFTER the line "source /ligo/cdscfg/stdsetup.sh" A complete list of aliases can be found by entering the "alias" command with no argument (in a terminal window, of course). I have also changed the setup scripts to recognize a different operating system, but this should not affect any users and is in place for testing candidates for the next control room computer OS.
