Commands
cd
target_directory
Change directory. This command makes target_directory your current working directory. It is a strong contender for the single most commonly used command in Linux. target_directory may be either a relative path, an absolute path, a shell symbol, or a shell variable.
Example: In the examples on the usage of the cd command presented next, assume that the shell variable $BOB stands for /home/bob. The directory tree is the same as the sample directory tree printed in the front of this chapter:
| Starting Directory | target_directory Type | Example Command | Ending Directory |
|---|---|---|---|
| /home/shawkins | relative | cd linux | /home/shawkins/linux |
| /home/shawkins | absolute | cd /home | /home |
| /home/shawkins | shell symbol | cd .. | /home |
| /home/shawkins | shell ... |
