Command of the day: column

Often I come across a new command which I think Wow! I always wanted to know how to do that.

I decided that I will blog about them and that way I will have a record for next time when I forget how to do it.

So my first command of the day I is one I saw on a Red Hat post. It can show the contents of a file tabulated into easy to read columns.

Example:
cat /etc/passwd | column -s : -t


Now you are probably aware of the <tab> character, often entered as \t or in bash as $'\t'. It will advance the cursor to the next tab stop which is traditionally every 8 characters. Well what if you have a tab delimited file but some data is longer than 8 characters and some it less. Well when you look at it, the output will be all over the place.

Using column you can get all your tab columns to line up like this:
cat data | column -s $'\t' -t
Note: for this to work correctly you must have a value in every column (perhaps a bug?)

  49. "cut" command can be used for these situations. For this example we can use grep -i client3 | cut -f 3 to find profession of client3. Same way we can see client2's name and surname at the same time by use grep -i client2 | cut -f 2 Because there is only one "space" character between name and surname and cut -f command use "tabs" as a separator.
