problem when using '|' to pipe command lines.

[Brian MacWhinney]

Dear Y. J.,
    The piping symbol is intended to be used in a single command within a single line.  It passes
data from one program to the next through a "data pipe".  It is not relevant to batch file usage.  
In your case, you want each of these commands on a separate line.  You can put these in a 
batch file, but if you use the -re switch properly, my guess is that you could just do this all through
a few commands you type in.  You may also want to use the +1 switch to avoid cluttering up your
folders with intermediary files.  But make sure you copy the whole corpus first in case the +1 switch 
makes an error.

For this type of work, you may also want to use a REGEX editor such as BBEdit that gives you more
power than CHSTRING.
