  • Requires: curl xsel access to the internet(http://transfer.sh) This is an alias utilizing the transfer.sh service to make sharing files easier from the command line. I have modified the alias provided by transfer.sh to use xsel to copy the resulting URL to the clipboard. The full modified alias is as follows since commandlinefu only allows 255 characters: transfer() { if [ $# -eq 0 ]; then echo "No arguments specified. Usage:\necho transfer /tmp/test.md\ncat /tmp/test.md | transfer test.md"; return 1; fi if tty -s; then basefile=$(basename "$1" | sed -e 's/[^a-zA-Z0-9._-]/-/g'); curl --progress-bar --upload-file "$1" "https://transfer.sh/$basefile" |xsel --clipboard; else curl --progress-bar --upload-file "-" "https://transfer.sh/$1" |xsel --clipboard ; fi; xsel --clipboard; } Show Sample Output

  • If you have servers on Wide Area Network (WAN), you may experience very long transfer rates due to limited bandwidth and latency. To speed up you transfers you need to compress the data so you will have less to transfer. So the solution is to use a compression tools like gzip or bzip or compress before and after the data transfer. Using ssh "-C" option is not compatible with every ssh version (ssh2 for instance).

  • -L RATE, --rate-limit RATE Limit the transfer to a maximum of RATE bytes per second. A suffix of "k", "m", "g", or "t" can be added to denote kilobytes (*1024), megabytes, and so on. It must be an integer.

  • Speaks whatever comes in via stdin (-v pt = portuguese, default = englisg) ..speech part of keyboard event talker. Made to accomplish a simple alarm central based on a cheap keyboard circuit. This way I have one zone per direct keypress. Depends on keypress.sh. It speaks out loud wich zone (key) has been pressed ( faulted ). Here is keypress.sh : #!/bin/bash # keypress.sh: Detect a user keypress ("hot keys"). echo old_tty_settings=$(stty -g) # Save old settings (why?). stty -icanon Keypress=$(head -c1) # or $(dd bs=1 count=1 2> /dev/null) # on non-GNU systems aplay -q /home/mm/bash/beep-1.wav echo echo "Chamada quarto \""$Keypress"\"." echo stty "$old_tty_settings" # Restore old settings. # Thanks, Stephane Chazelas. exit 0
