Hi,

I am working on script which can ignore Case sensitivity. suppose if user enter Linux or LINUX, scripr should accept both ways.

I use:
grep -i "[linux]"
grep -i "[LINUX]"


its not working. My script is not accepting Linux. its not accepting small letters linux.

can anyone help me?


thanks

Your square brackets need to be escaped and then I am sure that it will work. The filename/s to search go after the pattern to search for of course. :).

It will happily find [linux], [LINUX], [LiNuX] etc.

nope. not working
thanks anyways

here is my code:

li=`echo $userinput | grep -i "\[linux\]"`

can anyone can help this?

why the square brackets?
in=`echo $input|grep -i linux`
if [[ $? -eq 0 ]]
then
echo "match"
fi

I sidelined myself and assumed he was wanting a match of linux LINUX etc with square brackets - it must be getting late.

In the UK def late. Lunchtime here :)

good work! thanks for your help!

Chrism01,
Def late= > 3.30am UK local time, well after supper and too long before breakfast - not a bad time to consider sleeping. :) PAix

Hi

what happen if i want to check two arguments?

in=`echo $input|grep -i linux`
in=`echo $input|grep -i fedora`
if [[ $? -eq 0 ]]
then
echo "match"
fi


its not working at all.

thanks

$? is the status of the last run cmd, so you'd have to check each grep separately.
Perhaps you could expand on why you are doing this?

If you want to check that $input includes both "linux" and "fedora" :
