Use one loop get the variable assignment
Code:
        for var in {1..3}
        do
                lspci -nn |awk -v i=$var '/8086:10a7/{split($1,a,"[:.]"); print "0x"a[i]}'
        done

it will output
Code:
0x01
0x00
0x1

I want to let bus=0x01 slot=0x00 fun=0x1, How to modify this loop?


I know it can be get by


Code:
bus=`lspci -nn |awk '/8086:10a7/{split($1,a,"[:.]"); print "0x"a[1]}'`
slot=`lspci -nn |awk '/8086:10a7/{split($1,a,"[:.]"); print "0x"a[2]}'`
fuc=`lspci -nn |awk  '/8086:10a7/{split($1,a,"[:.]"); print "0x"a[3]}'`

But Can we get it in one loop? or use one line like python (a,b,c) ={something"

Thanks

Code:
lspci -nn |awk -v i=$var '/01:00.1/{split($1,a,"[:.]"); print "0x"a[1] " " "0x"a[2] " ""0x"a[3]}' |xargs -n 3 |read bus slot func

The previous post only works in ksh (last pipe element is in current context).
"eval" works in all sh derivates:
Code:
bus=slot=fuc=""
eval `
lspci -nn |
awk '
/8086:10a7/{split($1,a,"[:.]"); print "bus=0x"a[1],"slot=0x"a[2],"fuc=0x"a[3]}
'`

Try this while loop:
Code:
lspci -nn |awk '/1002:438/ {split($1,a,"[:.]"); for (i=1;i<=3;i++) printf "0X%02X ",a[i]; printf "\n"}' |while read bus slot fuc; do echo $bus, $slot, $fuc; done
0X00, 0X0C, 0X00
0X00, 0X0D, 0X00
