Save image from clipboard using xclip in cli

xclip -selection clipboard -t image/png -o > image.png

[options]

1) -selection

specify which X selection to use, options are "primary" to use XA_PRIMARY (default), "secondary" for XA_SECONDARY or "clipboard" for XA_CLIPBOARD 

Note: -se can be used as short form of selection

From man page: Options can be abbreviated as long as they remain unambiguous. For example, it is possible to use -d or -disp instead of -display. However, -v couldn't be used because it is ambiguous (it could be short for -verbose or -version), so it would be interpreted as a filename.

Since -s can be -selection or -silent hence minimum -se is required.

2) -t, -target

specify a particular data format using the given target atom.  With -o the special target atom name "TARGETS" can be used to get a list of valid target atoms for this selection. 

List available targets for available copy: xclip -sel clipboard -t TARGETS -o
