This set of commands was very convenient for me when I was preparing some xml files for typesetting a book. I wanted to check what styles I had to prepare but coudn't remember all tags that I used. This one saved me from error-prone browsing of all my files. It should be also useful if one tries to process xml files with xsl, when using own xml application.

In the above example all files have 4 lines. In "file1" consecutive lines are: "num, 1, 2, 3", in "file2": "name, Jack, Jim, Frank" and in "file3": "scores, 1300, 1100, 980". This one liner can save considerate ammount of time when you're trying to process serious portions of data. "-d" option allows one to set series of characters to be used as separators between data originating from given files.

Not a discovery but a useful one nontheless.

In the above example date format is 'yyyymmdd'. For other possible formats see 'man date'.

This command can be also very convenient when aliased to some meaningful name:

alias mkdd='mkdir $(date +%Y%m%d)'
blockdev --rereadpt /dev/sda
