Hi, Strange things:
i3: okn$ ls -R | grep -h "dof" | cat > dtext.txt
-bash: cat: command not found
or then I get this:
i3: okn$ find . -type f -print | grep -c
-bash: grep: command not found
but this is not happening all the time, i remember grep or cat did work once or twice...
What's going on here?
OS 10.7.4; repaired permissions
Any assistance much appreciated!

Mac OS X (10.7.2)
>cat -vte will display invisible and control characters
Tried that, thank you, but nothing strange here.
Also I took away a SHORTKEY which I had in Things, a Mac OS X app,
where the shortkey was ALT - SPACE.
Well maybe when writing the pipe, which is done on my keyboard with: ALT - 7 and when lifting the fingers off the 7 to press the SPACE, something was too fast, possibly.
Maybe related is the fact that on quite a few occasions on my webpages, empty spaces (but even between letters) something produces an " Â ", ie. an A with a roof on it, like you need in French, â = circonflex.
Now I never wrote this  -thing, it just introduces itself into the text sometimes.
Anyway, I'm glad for all the help I got and can now use again the grep and other commands in the terminal!

If you're encountering random characters in your data input, it would appear you have a problem with your keyboard, with OS X, or with your Mac hardware. If the random caracters are arising in your data output, then you're looking at some sort of problem arising somewhere between where your data is stored and the OS X rendering; with OS X or with your storage.
Swap your keyboard for a different USB keyboard, and see if things start working.
What are the results of the following commands?
echo $PATH
/bin/launchctl getenv PATH
/bin/cat /private/etc/paths
/bin/ls /private/etc/paths.d/Your PATH variable is set, but is not being exported to subshells. What do you get from this:
export -p | /usr/bin/grep PATH
And this:
( echo $PATH )
-bash: cat: command not found (or grep)
