Hi all,

i would like to know if it is possible to pass many string arguments for grep -v.

For example from my logs i need to extract all the lines which r not having "string1" and "string2".

this string list could be changed in future, so instead of changing the script i define them in a .prop file.

Now, instead of doing grep -v string1 a.log | grep -v string2 ....

is there any other way to do that ??

tnx

grep -v -e "string1" -e "string2" a.log

tnx Jim,

I got one more question, is there anyway we could do a split a string.

my idea is to have string like

prevent string1,string2,string3

get these substrings and build the grep command from a loop ...

if u have a better idea, would be welcomed...

tnx

You can use a file that is a grep "script"
Here is a file t.sed:

string1
string2
string3

grep -v -f t.sed a.log > newfile

find /path/to -name '*.log' | \
while read file
do
      cut -c -5  "$file"
done | sort -u > t.sed

grep -v -f t.sed /path/to/somewhere/a.log

tnx a lot Jim, its working kool..
