Shell Programming and Scripting

rdhanek,

For time being you can use something like this :

Code:

awk -v e="$express" '$0 ~ e {print}' LOG.txt

I am not figuring out why the same is not working with "grep".

Hi Panyam,

i don't think the issue is with grep, as i am getting the data if the else part of the code is executed.
The only issue is with first part of the code which i am using to get the yesterday's data, if the current time is less than 5 am.(as i njeed to get 5 hrs back data)
The first part also is printing the $ express correctly. There should an issue with the space somewhere which is causing ultimately grep not to pick any data.

Code:

if (( $stime < 5 ))
then
stime=`expr $stime \+ 18`
export express=`TZ=CST+24 date '+%m/%d/%Y'`\ $stime

But the awk statement which i mentioned is working well in both the conditions. You can test that which is similar to grep only.

panyam, i am getting a bailing out error with that awk command.

The same working fine for me ..can you recheck what you have tried.

Hi Panyam,

The awk statement is still giving me bailing out error. i am not sure if it is an issue because my box is SunOS.

Apart from this, the grep -w that you have suggested is working fine for both the instances finally.(it was not working for maual runs. I tried by cronning the script and it just worked fine. Not sure what was the issue when i run it manually. )

Thanks a lot for ur continuous support on This.

For the awk solution to make it work , use nawk or gawk and try.
