The following UNIX commmand are the ones most commonly used by Web Presence users while connected using a Telnet program. If you are using Microsoft Front Page then there are very few reasons to be worried about using Telnet or any of these commands. For specific usage use the man command below. | cd | change directory | | chmod | change file modes for user, group, and world i.e. "chmod 644 index.html". Each digit in the 644 is derived by three flags read, write and execute. Read=4, write=2 and execute=1. So 6 has read and write (4+2). The three digits equate to user(6), group(4) and world(4). It takes a bit to get comfortable with, but is very important. Many UNIX problems are caused by rights issues. | | chown | Change ownership of a file. This works very closely with chmod by establishing user and group access. "chown vision.vision index.html" would set the ownership of index.html to user=vision, group=vision. | | ls | list files and directories, use wildcards as well | | ls -l | list files and directories with more detail including ownership and rights | | man | this will bring up a man page for the command you are looking for i.e. "man ls" will show you information about the list command. Use the space bar to advance a page, the "b" key to go back and "ctrl-c" to end | | more | typically this command is used with the pipe character "|" to pause a directory listing i.e. "ls -l | more". be sure to use spaces before and after the | symbol | | passwd | Change User password | | pico | Simple text editor. "pico .procmailrc" will edit your .procmail file for adding Autoresponders, forwarders, etc. Make sure you are in the directory where the file exists or specify the path to the file. In UNIX paths are specified with a forward slash "/" in DOS and Windows they are specified with a backslash "\" | | pwd | show your current path | | which | Finds executables. The /usr/bin directory contains most of the executables that you will need to use. If you are unsure of what directory an executable is in, you can Telnet to cyweb.com and type 'which' followed by the executable name. For example to see a valid path for perl, type 'which perl'. |
