Copy and paste: `xsel`(see [here](/aw/os/shell/CopyPaste)) `xclip`.

## Pasting an Image with xclip
```bash
xclip -selection clipboard -t image/png -o > "image_file.png"
```
for which I have written a simple script
```bash
#!/bin/bash
o="$1"
if [ -n "$CLOBBER" -a -e "$o" ]; then
  /bin/rm -f "$o" || { echo "can't overwrite $o"; exit 1; }
elif [ -e "$o" ]; then
  echo "Not overwriting $o"
  exit 2
fi
xclip -selection clipboard -t image/png -o > "$o"
```
so that I need only type
```bash
paste_png image_file.png
```
or
```bash
CLOBBER=y paste_png image_file.png
```
(I could make it easier to clobber if I find I'm doing it alot, but of course you could `export CLOBBER=y` so that you don't have to use `CLOBBER` on every command. That's why I'm a fan of allowing the use of environment variables for most options of a command.)
