$ generaterandomchanges 3 file txt
[master f377b54] A random change of 27129 to file1.txt
2 files changed, 7 insertions(+), 1 deletion(-)
create mode 100644 file1.txt

git-graphlive <N optional, 10 default>

Perpetually loop git --no-pager log -<N> --graph --all --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s' --abbrev-commit --date=relative. It's like "tail -f" for git log. It's sometimes useful to have this on a split screen, showing the git one-line, ASCII art git graph.

$ git graphlive 5
* 6cad0b4 - (HEAD, master) A random change of 19964 to file30.txt
* c9fd401 - A random change of 16742 to file29.txt
* d5794af - A random change of 22469 to file28.txt
* b2110a3 - A random change of 32088 to file27.txt
* 75d01a9 - A random change of 12572 to file26.txt

historytailbash and historytailzsh

Perpetually loop through history. It's like tail -f for history. Comes in bash and zsh flavors. It's sometimes useful to have this on a split screen, showing the recent history of commands.

transpose <file>.csv

Generate a transposed *.csv file from an input file.

treelive <depth>

Perpetually loop tree, up to depth folders deep in the hierarchy.

welcome <name>

Prints a welcome message:
