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

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<&-
