Linux Commands

Remember Linux is Case Sensitive. myscript is different to MyScript.

Files and Directories

Copy files

cp from to

Examples

cp * mywork/

Copies all files in current directory to a sub directory called mywork.

cp myfile.txt myfile.txt.backup

Copies a file in the same directory and renames that file.

Copy directories

cp -R directory destinantion

The -R switch means recursive, meaning it will copy the contents of subdirectories as well.

Examples

cp -R dir1 dir2

This copy dir1 and it's contents to dir2. The end result is dir2/dir1/files

cp -R dir1/ dir2/

This copies the contents of dir1 (but not actually the direcory it's self) to dir2. Note dir2 must already exist. The end result is dir2/files

Moving Files/Directories

Move file to a different directory

mv myfile dir/to/move/to/

Move files using wild cards

mv file* dir/ (would move any file starting "file" i.e. file1, file2, file-that-should-be-moved)

Move the contents of a directory (files + sub directories) to another directory.

mv mydir/* mydir2/

As above but move to current directory

mv mydir/* ./

Renaming Files/Directories

To rename a file or directory, use the mv (move) command

mv myfile myfile-newname

mv dir dirnewname

Delete Files

To delete a file

rm <filename>
rm myjob.log

To delete multiple files

rm <partfilename>*
rm mywork* (delete all files starting with mywork)
rm *.log (delete all files ending with .log)

Delete Directories

To delete a directory (note the directory should be empty)

rmdir <directory>
rmdir myworkdir
