atomicstack / print-figlet-fonts.sh
Last active January 30, 2022 04:45
print examples of every installed figlet font. nicer than showfigfonts as it uses --termwidth and --filter border
#!/bin/bash
for f in /usr/share/figlet/*; do
font_name=$(basename "$f" | awk -F '.' '{print $1}')
message=" $font_name "
banner=$(toilet --filter border --font $font_name --termwidth "$message" 2>/dev/null)
[[ -z "$banner" ]] && continue
echo -e "$font_name:\n$banner\n"
done

atomicstack / ssh_config
Last active June 15, 2021 11:44
example Match stanza for ssh_config, which executes echo "hello world" before connecting to a (specific) host as a specific username. note: redirection to STDERR is necessary; using STDOUT will result in no output
Match host $HOSTNAME exec "echo 'hello world' 1>&2"
User $USERNAME
