How to output an array's content in columns in BASH.
- by Arko
I wanted to display a long list of strings from an array.
Right now, my script run through a for loop echoing each value to the standard output:
for value in ${values[@]}
do
echo $value
done
Yeah, that's pretty ugly! And the one column listing is pretty long too...
I was wondering if i can find a command or builtin helping me to display all those values in columns, like the ls command does by default when listing a directory (ls -C).
[Update]
Losing my brain with column not displaying properly formatted columns, here's more info:
The values: $ values=( 01----7 02----7 03-----8 04----7 05-----8 06-----8 07-----8 08-----8 09---6 10----7 11----7 12----7 13----7 14-----8 15-----8 16----7 17----7 18---6 19-----8 20-----8 21-----8) (Notice the first two digits as an index and the last one indicating the string length for readability)
The command: echo " ${values[@]/%/$'\n'}" | column
The result:
Something is going wrong...
