Tips and Tricks for Working on the Command Line

"Renaming files is one thing that a good GUI file manager appears to have over the CLI. Usually clicking on a file name will give you the opportunity to edit the name in order to rename it, which is great for files with long names. This can be done easily in a shell too, either by using tab expansion or with this little trick:

$ mv thisisareallylongfilename{,.txt}

"This will move the file "thisisareallylongfilename" to "thisisareallylongfilename.txt" without having to type it twice."
