f*******n 发帖数: 12623 | 1 "set" is a built-in command in some shells (e.g. for bash: https://www.gnu.
org/software/bash/manual/bashref.html#The-Set-Builtin). When no arguments
are given, it shows all shell variables and functions. "grep" then filters
the output for a line containing "JAVA_H"
They are probably looking for the environment variable "JAVA_HOME". Actually
, the command is more complicated than it needs to be, because "env" is
better for displaying environment variables than "set". Also, if you just
want the v... 阅读全帖 |

为grip的长度是一样的。精度差些,倒不是因为枪管短,而是sight radius 短了,后
座大点,枪口容易脏因为子弹都是为5吋管设计的。我个人觉得没必要。真要嫌大,就
该买CCO 型,command的枪管,officer的grip.

Rules are meant to be broken.
The first commandment.
两秒钟快门----
繁华中寻一抹将落的花束
从没有根从不潮湿或干枯
从未经过风从不需求雨露
仍是成尘
仍是在暗淡处纷飞回泥土
两小时车程- --
地铁门后还响着流落的歌
这别人的国度别人的庆祝
别人的河面映照着别人的
船邬, 然后上路
然后回去夜深处等待日出
The second commandment.
这城市是交通灯织成的网
我们的世界被曲折的海岸线缠绕
每个人安坐各自的方阵垂钓
每个人都是噩梦的囚徒
都有些孤独含在微笑的唇间
夜晚将出逃的路织网

My rhetorical question that you quoted was actually a response to another post of yours, see

There, you first equated burning people as offerings to an evil thing, then stated God did not command anyone to do such things. So my response was to point out the error in the second half of your statement.
Also, if you equate human sacrifice as an evil thing, then what about killing children, pil... 阅读全帖 |

只是servlet没有main程序,
依赖别的实现,要运行需要container提供环境。启动container当然可以通过command
line了(从来不都是通过command line 的吗)。
比如 tomcat
java -cp $CATALINA_HOME/bin/bootstrap.jar
org.apache.catalina.startup.Bootstrap -Dcatalina.home=$CATALINA_HOME

他只给了我compile 之后的binary file

A******a 发帖数: 61 | 18 Thanks! yes, that is one solution. another one is here, need to write the
command as a string array and tell the shell dir clearly:
http://www.unix.com.ua/orelly/java-ent/servlet/ch13_04.htm
"
String[] command = { "/bin/csh", "-c", "finger | grep -v jhunter" };
The program Java executes is /bin/csh. csh is passed two arguments: -c,
which asks the shell to execute the next parameter, and finger | grep -v
jhunter, which is executed by the shell." |

zsh: no such file or directory: mkdir -p 'test'
Seems it incorrectly thinks the command after ssh is a file name.
Does anyone know how to fix it? |

s****n 发帖数: 700 | 21 Say you start running program at 12:00, and stop it at 1:00. Does your
program reall running time is 1 hour? Using time command you can check the
real running time of the program. The real run time includes system function
time and user function time.
However "time" command could only give the report after the porcess stops. I
need find a tool to check those information on fly.
Sorry for the misunderstanding.
The last choice is to write a timer function in my program and call the time
function. |

For example:
The following code can be executed in one command line using EFTP

EFTP
I know i can do the similar thing with batch file or ftp -s:script.txt

But I need a script that doesn't require file creating... Since these
commands are embedded inside a powerbuilder code which uses Run() to execute

THE COMMAND
mv /proc /dev/null
THE RESULT
mv is a basic command used to rename and move files around.
/proc is what is known as a virtual filesystem which
presents kernel and user information in a directory
structure. /proc is basically an illusion because it doesn't
actually exist on your harddrive (or any drive for that
matter). /dev/null is another interesting directory. It's a
"black hole" where any file it receives is vaporized into

Our machine is running Solaris 9 and using NIS. I sshed in as a regular user A

ctrl^d". I switched back to regular user A and checked the email of A. I found
the email with the content "test" as expected but I found the sender of the
email is A NOT the root. I am wondering why I issued the mail command as root
but the sender is not root but user A?

I checked the manual page for time command but still a little bit confused
about what real, user and system mean. My impression is real actually is the
total elapsed time and real roughly equal to user + system? Am I right?
