blank spaces

Scala functions to repeat a character n times (blank padding)

Earlier today I needed a function that would return a desired number of blank spaces so I could “pad” some output as desired. For some reason my mind went blank and I forgot about using a printf-style solution, and it quickly went to, “How can I write a Scala function to return n number of blank spaces?”

Note: If you just want the “best” solution, please scroll to the bottom of this article.

A Bash ‘for’ loop to iterate over a file that has blank spaces in its lines

I just had to write a Linux bash shell script that has a for loop that reads a file, and that file contains lines with blank spaces in it. This sounds simple, but blank spaces cause major problems in a Bash for loop.

Fortunately there’s a simple solution: Before the for loop, declare the input field separator to be a newline character, as shown in this for loop code:

Handling spaces in Linux shell script input (and for loops)

Linux shell script FAQ: How can I deal with spaces (blank spaces) in my input data when I'm writing a shell script for loop or while loop?

I was just working on a Linux shell script, and ran into the ages-old problem of handling data that has spaces (space characters) in it. I run into this any time I try to read a data file with blank spaces in it, or when I run into files and directories with spaces in their names. Whenever I try to work this data like this in a shell script for loop, the spaces always ruin what I'm trying to accomplish.
