Re: egrep question

Folks,

I believe we may be missing an issue further up in this code that will not
work.

Look at the for loop on line 22.

If you do a "for name in `cat somefile`

and the lines in some file have spaces, then you WILL get $name that is

You cannot do it that way. You need to use a while loop and quote your
variable

Actually, this is even easier in PERL.

But, if you want shell program, I can send you an example of how to hand
lines in file1 and file2 that have spaces.... Just have to get back to my
office and pull a few scripts to make sure I don't
lead you astray.

egrep question






I have two files which have titles of books.
I want to check the book titles in one file to see if the title is in the
other file.
The book titles have spaces, periods, etc.

I wrote a script but I am having a problem getting the title in a form to
'egrep' to the other file.
Titles examples are like:

Script is called "check.file.to.file" and is as follows
and is run check.file.to.file name-of-file-1 name-of-file-2

1
2 if [ "$1" = "" ]
3 then
4 arg=0
5 echo "No args..Args are file-name file-to-check"
6 exit
7 else
8 arg=1
9 file1=$1
10 fi
11
12 if [ "$2" = "" ]
13 then
14 echo "Need 2nd argument for file-to-check"
15 exit
16 else
17 file2=$2
18 fi
19
20 # for name in `cat $file1 | cut -f1 -d' '`
21
22 for name in `cat $file1`
23 do
24
25 # egrep -w $name $2 > /dev/null
26 egrep $name $2 > /dev/null
27 grepresult=$?
28
29
30 if (($grepresult == 0))
31 then
32 echo $name " is IN "$2
33 # egrep -w $name $2
34 else
35 echo $name " NOT in "$2
36 fi
37
38 done

Is seems the problem is at line 32. How do you make the $name variable in
line 32
quoted?
