| cd |

| pwd |
The pwd command prints your current (or present) working directory.
Usage: Simply type pwd and hit return to display your current working directory.

| ls |
[directory]
The ls command lists the files and subdirectories in the directory you specify. If no

Usage: The ls command will display all files in the current working directory -
simply type ls and hit return. You can also add some additional arguments to customize
the list display.
If you type ls -F it will append a forward slash to the subdirectory names so you can
easily distinguish them from file names.
If you type ls -a it will show all hidden files. Hidden files begin with a dot
(.), such as .htaccess files.
If you type ls -l it will show detailed information about each file and directory,
including permissions, ownership, file size, and when the file was last modified.
You can also mix the arguments. If you type ls -aF you will see a list of all file
names (including hidden files) and a forward slash will be appended to directory names.
DOS Equivalent: dir
|
| cat |
[filename]
The cat command displays the contents of the filename you specify. If you want to
display the file one screen at a time try cat [filename] | more or simply more
[filename] (you may have done this at a DOS prompt- type [filename] | more).
DOS Equivalent: type
|

Simply type mkdir [directory name] and hit return.

| cp |
[source-file] [target-file]
The cp command copies a source-file to a target-file. Simply type cp [source-file]
[target-file] and hit return. You can specify pathnames as part of the file specification.
If target-file exists it is overwritten.
DOS Equivalent: copy
|
| mv |
[source-file] [target-file]
The mv command renames a file or moves it to a new location. Simply type mv [source-file]
[target-file] and hit return. You can specify pathnames as part of the file specification.

|
| grep |
[pattern] [filenames]
The grep command finds lines in files that match specified text patterns. Simply type grep
[pattern] [filenames] and hit return. You can specify pathnames as part of the file
specification. For example if you want to search for the pattern gif in all html files
in your current working directory, you would type grep gif *.html and hit return. The
grep command would then list all occurrences of gif it finds in .html files in
the current working directory.
DOS Equivalent: find
|
| tar |
[options] [tarfile] [files]
The tar command copies a file or files to or from an archive. To put all the files in a
directory into one tar format file, simply type tar -cvf tarfile directory at a telnet
command prompt and replace tarfile with the name you want to call your archived file,
and replace directory with the name of the directory that contains the files you want
to compress.
To extract the files from a tar format archive, simply type tar -xvf tarfile at a
telnet command prompt and replace tarfile with the name of the archived file you are
extracting.
For example, you could type tar -cvf pages.tar htdocs at a telnet command prompt to
archive the files in the htdocs directory to a tar format file called pages.tar.
To view the contents of the pages.tar tarfile without extracting them, type tar -tvf
pages.tar. This will display all files that are included in the tar archive.
You could also type tar -xvf pages.tar at a telnet command prompt to extract into
the current directory the files in the archive pages.tar.
|
| zip |
[options] [zipfile] [files]
The zip command compresses a file or list of files into a zip format archive file. This
command is compatible with pkzip on a PC. Simply type zip zipfile file1 file2 file3 at
a telnet command prompt and replace zipfile with the name you want to use for your
compressed zip archive file, and replace fileX with the name of the file(s) you want to
compress into the zip archive.
For example, type zip backup.zip home.html index.html at a telnet command prompt to
compress and archive the files called home.html and index.html into the file
called backup.zip.
DOS Equivalent: pkzip
|
| unzip |
[options] [zipfile]
The unzip command extracts a zip format archive file. This command is compatible with
pkunzip files from a PC. Simply type unzip zipfile at a telnet command prompt and
replace zipfile with the name of your zip format archive file.
For example, type unzip -aL old.zip at a telnet command prompt to extract files
contained in the archive called old.zip. The -aL are options that are generally
useful when unzipping files created on a PC.
DOS Equivalent: pkunzip

The compress command shrinks a file or files into compressed versions to save space on your
Virtual Private Servers. This command is good for you to use on your log files when they get
very large. Simply type compress filename(s) at a telnet command prompt and replace
filename(s) with the name of your files you want to compress.
For example, type compress access_log agent_log at a telnet command prompt to compress
the access_log and agent_log files. The compressed files will then be
access_log.Z and agent_log.Z.
