Do not use find
Test your script with filenames that have spaces in them. Get it right.
Q 1: Upload count.bash
$ reextend .log .txt
Would cause install.log to be renamed to install.txt, and
$ reextend A B
Would cause TADAA to be renamed to TADAB . It would also cause file.A to be renamed file.B .
The script should print out error messages as is appropriate if there is any problem with the command line arguments. Test the script with a range of different parameters, including incorrect parameters or missing parameters.
hint: See Parameter Expansion in the bash man or info page.
hint: See what ls -1 does.
Q 2: Call this script reextend , and upload it w/your lab.
Led Zeppelin - Over the Hills and Far Away.mp3
, all in the same directory. What you really wanted was to have the songs in directories by artist, and just the song name for the filename:
Led Zeppelin/Over the Hills and Far Away.mp3
So, write a script that looks in the current directory only for mp3 files, breaks the filename out into artist and song title, creates the appropriate directory (if it doesn't already exist), removes the artist and the first ' - ' from the filename, and moves it into the directory.
Q 3: Call this script organiseMusic , and upload it w/your lab.
Get the sha-bangs just right. We'll worry about permissions.
