Hi pkwan, Martin, there is some mis-understanding, in fact what I want is using vim to run, see below:<br />
<br />
vim '+1,100dd' '+wq' del100.log<br />
<br />
I failed to delete first 100 lines, what was wrong my script??<br />

I think vim does not recognize &quot;+1,100dd&quot; as a valid command.<br />
<br />
You may try if the following works:<br />
<br />
vim '+d100' '+wq' &nbsp;test.txt
</div>

Looks like you have the numbers and the d in the wrong place.<br />
It should be:<br />
vim &nbsp;'+1,100d' &nbsp;'+wq' &nbsp;del100.log
</div>

It should be:

Hi, I want to have a shell script to edit and delete 100 lines everyday and as same filename, this is something like:<br />
<br />
vi del100.log<br />
100 dd<br />
:wq<br />
<br />
P.S: This log file is active all the time and lock by the application, but no problem to delete 100 lines by manually.

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).
