工作学习 / 学科技术讨论 / su and awk: HELP!Hi,
I would like to run awk with different user identities, so I invoke awk from su as root:
# su alelai -c "awk '($0 ~ /sbtorsvr329/) {print $1}' /home/alelai/.ssh/known_hosts"
the command return silently.
but the same awk command gives the following output when run directly:
sbtorsvr237{alelai}: awk '($0 ~ /sbtorsvr329/) {print $1}' /home/alelai/.ssh/known_hosts
sbtorsvr329,172.22.12.187
Can anybody point out what is wrong?
Thanks in andvance.

集体 崇拜 显得没有诚意，要一个个败过来

帮助菜鸟是小鸟的责任，老鸟忙着搞个人崇拜了
