[英]how to find the user is logged in as root in Linux using bash script?
[英]How to know if a process is user or root in bash, linux
我需要知道一個過程是否來自用戶。 我正在使用此代碼:
#c is the PID
Aid=$(cat /proc/$c/status | grep -e ^Uid)
Uid="Uid: 0 0 0 0"
if [ "$Aid" != "$Uid" ]; then
echo "is from user"
fi
但是我對字符串中的“選項卡”不太滿意,我認為這可能會導致某些意外行為。
還有其他方法嗎?
您可以在不使用ps -o uid= -p $pidhere
進行解析的情況下獲取某個pid的UID:
mypid=1
if uid=$(ps -o uid= -p "$mypid")
then
if [[ $uid -eq 0 ]]
then
echo "The process runs as root"
else
echo "The process runs as something else"
fi
else
echo "The process doesn't exist"
fi
