我想在一行中打印出iwconfig的比特率和信号电平,并用空格分开。到目前为止,我使用不同的命令分别打印比特率和信号强度:
iwconfig wlan0 | awk -F'[=] +''/比特率/ {打印$ 4}'
iwconfig wlan0 | awk -F'[=] +''/信号电平/ {打印$ 7}'
,结果将是
54
-43
是否有可能让它们像这样:
54 -43
我该怎么办?谢谢

One simple way is to assign the output of your commands
to variables. That way, you can print them out however you want.
I just tested this on Ubuntu 12.4. Note the back quotes around
the commands.
v1=`iwconfig wlan0 | awk -F'[ =]+' '/Bit Rate/ {print $4}'`
v2=`iwconfig wlan0 | awk -F'[ =]+' '/Signal level/ {print $7}'`
echo $v1 $v2
