E.g. grep does not work here (always):

$ cat /etc/X11/xorg.conf | grep device
bash:  grep: command not found
$ grep
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.

Same thing with less command:
$ lspci | less
bash:  less: command not found
$ less
Missing filename ("less --help" for help)
