Why I am getting this error message: bash: find/usr/share/help: no such file or directory
Commands and their arguments must be separated by whitespace - not
find/usr//share/help/
but
find /usr/share/help/
You should also enclose shell wildcards like *.page in quotes when you use them as arguments to the find command - otherwise the shell will try to expand them to names of files in the current directory. So
find /usr/share/help/ -name '*.page'
