Search for a string with different cases
Hi Guys,

I am using the following command in a script.

Code:
cat $sql_file_path"/"${sql_file_list[$i]} | grep "ABCDE"

but it returns only exactly matching lines (ABCDE)

how can i modify this single line so it will return if it finds a matching string with any case.

eg: Abcde, abCDe, abcdeE, ...

Thanks

Code:
grep -i 'ABCDE' somefile

if your version of grep supports -i.

One more question. how can i search for this in a particular line in the file. for an instance if i wanted to search in the third line? or maybe in first five lines?

Thanks

search in the third line:
Code:
sed -n '3,3 {/text_to_search/I p}' filename

search in first five lines:
Code:
sed -n '1,5 {/text_to_search/I p}' filename

Hi Yogesh. it works fine. Thanks. but it doesn't return any error code if it was not found. for an instance if i used grep it would return "1" if the text was not found. is there any way we can get an error code for this if not found? thanks

Got over this by combining grep

sed -n '3,3 {/text_to_search/I p}' filename | grep -i "text_to_search"

Thanks guys Smilie
