| Another option is to use jq: | |
| # Reference https://stackoverflow.com/a/34407620/13287790 | |
| $ printf %s 'encode this'|jq -sRr @uri | |
| encode%20this | |
| $ jq -rn --arg x 'encode this' '$x|@uri' | |
| encode%20this | |
| -r (--raw-output) outputs the raw contents of strings instead of JSON string literals. -n (--null-input) doesn't read input from STDIN. | |
| -R (--raw-input) treats input lines as strings instead of parsing them as JSON, and -sR (--slurp --raw-input) reads the input into a single string. You can replace -sRr with -Rr if your input only contains a single line, or if you don't want to replace linefeeds with %0A: | |
| $ printf %s\\n 'multiple lines' 'of text'|jq -Rr @uri | |
| multiple%20lines | |
| of%20text | |
| $ printf %s\\n 'multiple lines' 'of text'|jq -sRr @uri | |
| multiple%20lines%0Aof%20text%0A | |
| Or this percent-encodes all bytes: | |
| xxd -p|tr -d \\n|sed 's/../%&/g' |
very handy!
Maybe a shorter version:
echo 'encode this' | jq -Rr @uri
Maybe a shorter version:
echo 'encode this' | jq -Rr @uri
Better use printf because echo appends a possibly unwanted \n at the end.
Normally I do this
echo -n 'encode this' | jq -Rr @uri

Ti lovvo smodatamente.
