Replace CTRL-A in a file while in a screen session
echo -e “\u0001” | cat -v # ^A cat -v 000001 | tr ‘^A’ ‘\t’ | head Inspiration: http://stackoverflow.com/questions/31460818/creating-a-ctrl-a-delimiter-file Note: Within the same day, this strategy both worked then failed. YMMV More reliable would be to get into a non screen session and do “ctrl-v then a”
