ASTi Telestra 4 Target Operations & Maintenance Manual (Ver. 1, Rev. K)

Appendix D: Useful Linux

Commands

The following commands are useful when navigating the Target via the command line.

Typing ‘ls’ at the command line displays the files that are in a particular directory. It is similar to

the ‘dir’ command in DOS. Common variations include ‘ls -l,’ which displays more

information about the files and ‘ls -a,’ which will display all files and directories including

“hidden directories.”

pwd

This command returns the full path that you are currently in. It is useful for seeing where you are

in the directory tree.

cd_newdirectory

The Change Directory command allows the user to navigate through the file system. It is similar

to ‘cd’ in DOS but there are a few differences. For example, Linux is case sensitive. As a result

the command:

cd Folder1

is not the same as

cd folder1

There is a shortcut to go up one folder which is the ‘..’ expression. Similarly, they can be

combined to go up multiple folders in a single line. See example below:

1 2 ... 37 38 39 40 41 42 43
