A common way to save all filenames in a directory is to do:
ls > filenames
My directory looks like so:
$ls | head TCGA-A1-A0SN TCGA-A1-A0SN.xml TCGA-A2-A04N TCGA-A2-A04V TCGA-A2-A0CM TCGA-A2-A0CM.xml
However when I call “ls > filenames” on my shell (bash, CentOS) it returns a file like so:
^[[0m^[[01;34mTCGA-A1-A0SN^[[0m ^[[0mTCGA-A1-A0SN.xml^[[0m ^[[01;34mTCGA-A2-A04N^[[0m ^[[01;34mTCGA-A2-A04V^[[0m ^[[01;34mTCGA-A2-A0CM^[[0m ^[[0mTCGA-A2-A0CM.xml^[[0m
I would like to know 1) Why this happens, and 2) What I can do to save the filenames in regular text format.
EDIT: product of calling “alias ls” is
$alias ls alias ls='ls --color="always"'
