HI,

I want to grep the contents of fileb from filea.

filbeb
5x4xxx371x31a43
4x40x037103a049
3x4x003710a0659
4x4x0x371a50912


filbea
5x4xxx371x31a43 3266000225
4x4003266000277 3266000277
4x400326x000499 3266000499
4x4003266000676 3266000676
4x4x0x371a50912 3266000777
4x40x037103a049 3266001819
4x40xx371057013 3266001820
4x4x00371056788 3266001821
3x4x003710a0659 3266001823



output should be as shown below

3266000225
3266001819
3266001823
3266000777



I used below code but giving error as Segmentation Fault (core dumped)


egrep -f fileb filea | awk '{print $2}' >> output


fileb count is 90535
filea count is 1591132

Pls help me

a=`cat filbeb`

cat filbea |grep ${a} | awk '{print $2}' > /tmp/output
