Shell Programming and Scripting

hi!!


I am getting an error while grepping.

The error is like "grep: RE error 41: No remembered search string."

Can u please help with it?

An e.g

# # #20090508234729# # # # # # # # # #7#919855198983# #71# #1758#1613# # # #serv:pps7a;vers:1;pid:0;af:3;vid:1117980591288184;Dvl:0;serType:0;recType:1000;a
mt:0;costType:1#



I am trying to grep "1117980591288184" in the above string.

I have more then thousand different numbers to grep in a very large file.
I want to know when does this error occurs in particular, because the data i am getting after grep is correct but still the grep code is throwing an error......y is it so?

for reference below is the code:-

while IFS= read -r line
do
grep -h "$line" /user2/200905/20090508*.znf >>/home/yesterday.txt;
done < /home/hrn_20090508.txt

Probably, it is caused when trying to evaluate the grep string read from the file as a regular expression. Does the file have empty lines...

I suggest you use

Code:

egrep -h "$line" /user2/200905/20090508*.znf >>/home/yesterday.txt 2>/dev/null
