Subject: grep Supplement for SCO UnixWare 2
Date: Tue, 15 Aug 2000 23:18:08 GMT



The following Support Level Supplement (SLS) is available for downloading 
from the "SLS" directory at ftp.caldera.com:

ptf4062a: grep Supplement 

URLs associated with this SLS are:

ftp://stage.caldera.com/SLS/ptf4062a.txt   
ftp://stage.caldera.com/SLS/ptf4062a.Z  


This SLS installs on the following platform(s):

             SCO UnixWare 2.01 - 2.1.3

Description:

This SLS addresses the following problem:

        When the pattern file named in a "-f" option is actually a pipe,
        it is possible for the grep or egrep command to fail to read all
        of the specified patterns, that is, it might read some, all, or
        none of the data supplied via the pipe.  This may cause incorrect 
        results to be produced.  No error message is generated.

        Two examples of problematical usages would be:

            $ echo $pat | genpat | grep -f /dev/fd/0 infile 
            $ grep -f <(echo $pat | genpat) infile          # ksh only

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
