Not until midway through a 3 hour build script, I’ll remember that I want to see something at the beginning of the output after it’s done. At this point I’ve exceeded the number of lines in my terminal so I can’t scroll up to see it (or the beginning is hard to find). Of course I can be better about storing my output, but I’ve always been curious if this were possible.
In a linux shell, is it possible to return the output of the last command. I realize I could have piped it or sent the output to a file, but my requirement is to retrieve that output after the command has been run.
Using csh, but would hear about any shell.
No. The output of a program never passes through the shell’s hands. Without redirection, it goes straight to the TTY. With redirection, it goes straight to whatever file or pipe it was directed to. The shell has no idea what the process sent to stdout/stderr.
