CS1K Rel 6 - Linux Command Line Notes
Directories:
Home Directory
- When you login as nortel your home directory is /home/nortel
- When you login as root your home directory is /root: this is different to /
- You can use the $HOME variable to refernce your home directory: cd $HOME
Locating Files
- Patch files need to be located in /var/opt/nortel/patch
- Application Log files are located in /var/log/nortel
- CPPM-Cores files system (/p /u /e) is located at /var/opt/nortel/cs/fs
- CD RPT log files are located in /var/opt/nortel/cs/fs/e/rpt/ (use rdopen/rdtail in PDT to view)
- DCH trace logs are located in /var/opt/nortel/cs/fs/u/trace/dch.log
- Deployment backup files /var/opt/nortel/deployment/deployed/"sys name"/backup
To change directories you use the cd command, but to make life easier and save typing, you can use the <TAB> key to automatically add the directory. Try this:- Type "cd /v" then hit the <TAB> key. Because there is only one directory begining with "v" the system will automatically change the line to "cd/var/" if you want to go further you can add the first letter of the next directory e.g. "cd /var/o" and again hit the <TAB> key. The line will not be updated to "cd/var/opt/" you can keep going till you have the full directory path. If there are two options, the system will BEEP and you will need to add another character and <TAB> again. This technique can also be used with commands such as copy (cp).
