LINUX命令报错

1、find: paths must precede expression

[root@localhost /]# find /u01/app/diag/tnslsnr/fossdb/listener/alert -name log_*.xml
find: paths must precede expression
Usage: find [-H] [-L] [-P] [path...] [expression]
[root@localhost /]#
[root@localhost /]# find /u01/app/diag/tnslsnr/fossdb/listener/alert -name 'log_*.xml'
进行查找资料，多文件的查找的时候需要增加单引号

[root@localhost /]# find /u01/app/diag/tnslsnr/fossdb/listener/alert -name 'log_*.xml'
2、find: missing argument to `-exec’ 或 find: 遗漏“-exec”的参数
[root@localhost /]#find /u01/app/diag/tnslsnr/fossdb/listener/alert -name 'log_*.xml' -exec rm -rf {}\;
find: missing argument to `-exec’

要这样
find /u01/app/diag/tnslsnr/fossdb/listener/alert -name 'log_*.xml' -exec rm -rf {} \;--这里要加空格

3、# scp
-bash: scp: command not found
新搭建的服务器上没有scp命令
在一台正常的服务器上运行如下命令
# which scp
/usr/bin/scp

# rpm -qf /usr/bin/scp

openssh-clients-4.3p2-72.el5
在有问题的服务器上运行如下命令
# yum install openssh-clients
或者从光盘上安装
# rpm -ivh
libedit-2.11-4.20080712cvs.1.el6.x86_64
# rpm -ivh
openssh-clients-5.3p1-20.el6.x86_64
4、sudo: sorry, you must have a tty to run sudo

使用不同账户，执行执行脚本时候sudo经常会碰到 sudo: sorry, you must have a tty to run sudo这个情况，其实修改一下sudo的配置就好了

vi /etc/sudoers (最好用visudo命令)

注释掉 Default requiretty 一行

#Default requiretty

意思就是sudo默认需要tty终端。注释掉就可以在后台执行了。
5、can't get address for localhost
X11TransSocketINETConnect() can't get address for localhost:6010: Name or service not known
