grep : having trouble with a single quote

Hi,
I search for the string below which contains a single quote,
some text '/home/myuser
in the file myfile.txt as another user with the grep command as follows
su - myuser -c "grep 'some text \'/home/myuser' myfile.txt"

I also tried using two backslashes
su - myuser -c "grep 'some text \\'/home/myuser' myfile.txt"
but to no avail, I still get
Unmatched '.
Does anyone have a solution for this silly problem?

Thanks,
C

Try this (not tested):

Code:
su - myuser -c "grep \"some text '/home/myuser\" myfile.txt"

Hi there,
Thanks for your suggested solution.
Unfortunately I get the same outcome
su - d3dadm -c "grep \"successfully loaded DB2 library '/db2/db2\" trans.log"
Unmatched '.
Regards,

Hi,
You didn't su - user,
so it's not working.
Thanks,

Hi tyler,
I found out the answer if anyone is interested
su - d3dadm -c "grep "\"successfully loaded DB2 library \'/db2/db2d3d\"" trans.log"
I only ever use csh for scripts as its nearly always guaranteed to be on all machines.
Thanks,
C
