Add usage examples to the README

[sharkdp]

For example:

• Searching for a substring: fd todo
• Searching for a substring in another location: fd apache /var/log
• Use fd as an alternative for ls -R: fd
• Searching all files (including hidden and ignored files): fd -HI ....
• Searching for a file extension (see also Add option to only search file extensions? #56)
• Piping output to xargs: fd -0 ... | xargs -0 du -h
• Show absolute paths (either via -a or by providing an absolute path as destination)

I'd be happy to help with this! Installing fd now so I can test it out.

[sharkdp]

@cravend Sounds great! Any help would be greatly appreciated.

[cravend]

@sharkdp sorry about this, but realized this might not work the best for me--currently windows only. Product looks cool though, good luck!

[deg4uss3r]

I can help with this! Would you like simple examples, or a fancy gif like the README already has :)

[sharkdp]

@cravend no worries. Thanks for considering. fd should work on Windows, though.

@deg4uss3r I think simple markdown code blocks or maybe static screenshots would be great.

Please add example how to find and delete files. Ideally translate this example to fd.

find . -iname "**.sw?" -delete   # delete vim swap files in current directory

[sharkdp]

That example in fd would be:

fd '\.sw.$' -x rm

Please always check what is going to be removed first (Your pattern also matches .swf Flash files, for example!):

fd '\.sw.$'

[marko-avlijas]

Thanks. Only -H is missing because vim swap files start with .

fd -H '\.sw.$'          # find all vim swap files
fd -H '\.sw.$' -x rm   #  find and delete all vim swap files

I think this is good addition to README.md
