Simple implementation of part of screen(1) by lending out the master end of a PTY over a UNIX domain socket. Detach with ^Q. dtch a nvim & disown atch a fbatt Battery charge indicator panel for the Linux framebuffer through /sys/class/power_supply. fbclock Clock panel for the Linux framebuffer. Renders PSF2 bitmap fonts. glitch PNG glitcher based on pngo. -c write to stdout -o PATH write to file -p broken Paeth predictor -f filter when reconstructing -r reconstruct when filtering -d LIST declare pattern of comma-separated filters -a LIST apply pattern of comma-separated filters -i invert after filtering -m mirror scanlines after filtering -y swap first and last scanline after filtering -x swap first and last pixels of scanlines after filtering hnel The tr(1) of PTYs, for remapping keys. Originally for preserving HJKL in alternate keyboard layouts. Toggle remapping with ^S. hnel '[]{}' '{}[]' vi klon Klondike solitaire for curses. BSD-only for arc4random_uniform. q quit u undo ' ' draw w waste a-d foundations 1-7 tableau ^M auto-foundation modem PTY wrapper with a fixed baud rate of 19.2 kbps. pbd/pbcopy/pbpaste TCP server which pipes into macOS pbcopy(1) and from pbpaste(1), and pbcopy and pbpaste implementations that connect to it. Used to share the macOS pasteboard over SSH with RemoteForward 7062 127.0.0.1:7062. This used to make nvim's "+ register work but they seem to have changed their detection. pbd & disown ssh tux.local pbpaste pngo PNG optimizer. Does not support interlaced PNGs. - Discards ancillary chunks - Discards unnecessary alpha channel - Converts unnecessary truecolor to grayscale - Indexes color if possible - Reduces bit depth if possible - Applies a simple filter type heuristic - Applies zlib's best compression pngo foo.png pngo -o bar.png foo.png pngo -c foo.png | xx scheme Color scheme for terminals. -a generate ANSI palette -t generate Terminal.app palette -h output HSV -x output RGB -g output PNG -c output C -l output Linux console OSC sequences -m output Mintty theme wake Broadcasts a wake-on-LAN packet to one of my machines. watch Executes a command each time files change.
