使用管理员权限创建的用户但出现权限被拒绝错误

我创建了一个具有管理员权限的用户。对于某些主机，Linux 命令可以无缝运行，但对于某些系统，输入命令时会显示权限被拒绝：

praveen.kumar@chn_lab:/home/admin$ free -m |grep Mem |awk '{print $3/$2 * 100.0}',
bash: /usr/bin/awk: Permission denied
praveen.kumar@mum_lab:~$ free -m |grep Mem |awk '{print $3/$2 * 100.0}'
53.9168

工作机权限：

praveen.kumar@mum_lab:~$ cat /etc/passwd
admin:x:1003:1000::/home/admin:/bin/bash
praveen.kumar:x:1004:1000:praveen.kumar:/home/praveen.kumar:/bin/bash

出现错误的机器权限：

praveen.kumar@chn_lab:~$ cat /etc/passwd
admin:x:1002:1000::/home/admin:/bin/bash
praveen.kumar:x:1011:1000::/home/praveen.kumar:/bin/bash

对于与管理员用户相同的用户，如何纠正此权限被拒绝错误？

praveen.kumar@chn_lab:~$ pwd
/home/praveen.kumar

praveen.kumar@chn_lab:~$ free -m |grep Mem |awk '{print $3/$2 * 100.0}'
-bash: /usr/bin/awk: Permission denied

是的，您的/usr/bin/gawk权限无效。

做：

sudo chmod 755 /usr/bin/gawk

然后它就会运行。
