| Jul 13, 2015 at 6:44 | comment | added | Celada | I realize that, but I felt it was necessary to stress the fact that $COLUMNS is not actually an environment variable, because it looked like the OP was expecting it to be one. It turns out the OP did indeed expect it to be one and ran into further problems because of that assumption.. | |

"The set builtin can perform the following tasks.... -Display variables that are available to the current shell. These variables comprise shell variables (variables not in the environment) and environment variables." (pp.1036). OP already said they are using set, so bash is assumed. | |
