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




[root@esbserver54 configuration]# cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.
