SYNOPSIS | |
Post gist: | |
gist.sh [-e <extension>] [-p] [-c] [-a] [-d] | |
gist.sh [-p] [-d] [-a] -f file | |
Retrieve gist: | |
gist.sh [-f <file> | -c] [-d] <gist-id> | |
Clone gist: | |
gist.sh [-l] [-p] [-d] <gist-id> | |
DESCRIPTION | |
With -f, gist.sh reads/writes files. | |
With -c, gist.sh reads/writes to the clipboard (xclip is required). | |
With -l, gist.sh clones the gist to a local git repository. | |
Otherwise, gist.sh reads/writes standard input/output. | |
If your git config contains github.user and github.token (see | |
https://github.com/account), they will be used to assign yourself as owner | |
of posted gists. Use the -a or --anon parameter to post anonymously. | |
OPTIONS | |
-f, --file | |
Read/write a gist from/to the specified file. Github guesses the gist | |
language from the filename, therefore -e is ignored. | |
-c, --clip | |
Read/write a gist from/to the clipboard. | |
-l, --clone | |
Clone a gist. | |
-e, --ext | |
When reading standard input or clipboard, specify an extension. Github | |
sets the gist language based on the extension e.g. "java", "rb", "py". | |
Ignored if -f is specified. | |
-p, --private | |
Make a gist private. When cloning, use the private clone URL to clone | |
the gist. Requires the gist to be non-anonymous. | |
-a, --anon | |
Post a gist anonymously, even if Github authentication data is | |
available in the global git config. | |
-d, --debug | |
Debug mode. Nothing is actually read or written to Github. | |
