Hey, does anybody know is there a way to remove a file while read?
Something like: rm file.txt -o - | cat - ?
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.

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; fgOr this, with shell file descriptors:
$ exec 3< file.txt; rm file.txt; cat <&3; exec 3<&-How do you mean by “remove it”? Delete the file node?
You can’t delete it before finish reading it. The most you can do is write a program to read one byte, then wipe that byte to zero.
why not just read the file, then remove it:
Not that I understand why you would want to do this anyway; it kind of doesn’t make any sense.
Just courious, it’s not something that will be useful, thanks.
