From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hey, does anybody know is there a way to remove a file while read?

Something like: rm file.txt -o - | cat - ?

You can open it, delete it, then finish reading it. The file will disappear from its folder but of course the data won't actually be deleted until you close it.

Like this, with bash job control:

$ cat file.txt & rm file txt; fg

Or this, with shell file descriptors:

$ exec 3< file.txt; rm file.txt; cat <&3; exec 3<&-
