If you want to share text you can do it with https://hastebin.com and then inside your .bash-aliases or similar define a function like
export HASTE_SERVER=https://hastebin.com
haste () {
a=$(cat)
curl -X POST -s -d "$a" $HASTE_SERVER/documents | awk -F '"' -v haste_server=$HASTE_SERVER '{ print haste_server"/"$4 }'
}
If you want to share somefile from commandline with
cat somefile | haste
and it will respond with e.g
https://hastebin.com/ibejajiful.bash
that points to the shared text from somefile. To get text down into a localfile again do
curl https://hastebin.com/raw/ibejajiful > somefile
and your have a local version of that file.
Notice that you should not share important information with this tool as it is not secure.
