shell使用ps -ef|grep xxx时不显示grep xxx进程的方法

流过昼夜 提交于 2019-12-03 17:30:18
在使用ps -ef|grep xxx时会将grep xxx的进程也带出来, 而在脚本中如果想要截取此命令结果的一部分,则grep xxx的进程会显得多余,如下: [root@localhost ~]# ps -ef|grep python root 2829 1 0 Feb28 ? 00:00:13 /usr/bin/python -tt /usr/sbin/yum-updatesd root 17714 17490 0 11:46 pts/0 00:00:00 grep python 加上awk命令截取python的路径那部分则结果如下: [root@localhost ~]# ps -ef|grep python|awk ‘{print $8}’ /usr/bin/python grep 多了grep那一行,那么可以在grep xxx后再加一个grep -v 'grep’来将其去掉,如下: [root@localhost ~]# ps -ef|grep python|grep -v ‘grep’|awk ‘{print $8}’ /usr/bin/python 如此,则grep 被去掉. 原文地址:https://blog.csdn.net/diyiday/article/details/83785118 来源: https://www.cnblogs.com/jpfss/p

Ps 中蒙版有哪些使用技巧?

这一生的挚爱 提交于 2019-12-03 11:01:41
蒙版除了抠图,也能创造一些神奇的效果。蒙版,顾名思义,就是蒙在图层上面的板子,把图片蒙起来,然后配合黑色画笔、白色画笔、灰色画笔在蒙版上涂抹,就可以隐藏、显示、半透明的展现图像中的部分内容。蒙版简单说,就是一个不单可以擦掉,还可把擦掉的地方还原的橡皮擦工具。 让图像一半变为黑白 复制背景图层—快捷键【Ctrl+J】,去色—【Ctrl+Shift+U】,添加图层蒙版,选择渐变工具【G】拉出一个黑白渐变。 让黑白照片里的彩色突出 复制背景图层—【Ctrl+J】,去色—【Ctrl+Shift+U】,添加图层蒙版,把需要突出的部分选中(用钢笔也行、用魔棒也行、根据实际情况来看),形成选区-填充黑色。注意一定要在蒙版图层上操作,不然就会出现没效果的的情况。(在这里给大家普及一个小知识,为什么填充黑色而不填充白色。因为在图层蒙版中,填充黑色为隐藏,填充白色为显示。这里是因为我们要做的是突出一部分彩色,所以我们把全图去色了的。我们只需要选择自己想要突出的部分,把它隐藏掉。在去色的图层上它就会消失,显示有颜色突出的部分是我们的背景图层。所以不要把黑色当成是显示咯!!!) 编辑:千锋UI设计 来源: https://www.cnblogs.com/leolei/p/11792350.html

What does TTY mean in the unix ps command?

坚强是说给别人听的谎言 提交于 2019-12-03 10:39:09
问题 When I run PS one of the columns output is TTY. What does this mean? In particular, how does as value of "??" compare with "ttys000"? I ask because I have a Java program execute sort via ProcessBuilder, and when this program is run via my IDE (IntelliJ) the process takes 5x less than when run as an executable jar outside the IDE. In each case I run ps when the sort is running and the only difference is the IDE creats a process with a TTY of ?? whereas the jar creates a process with TTY of

Determine the minimum across SIMD lanes of __m256 value

I am using AVX2 intrinsics, and have 8 floating point values in an __m256. I want to know the lowest value in this vector, and to complicate matters: also in which slot this was. My current solution makes a round trip to memory, which I don't like: float closestvals[8]; _mm256_store_ps( closestvals, closest8 ); float closest = closestvals[0]; int closestidx = 0; for ( int k=1; k<8; ++k ) { if ( closestvals[k] < closest ) {

Tight bounding box around PDF of MATLAB figure

Is there a simple way to get a tight bounding box around the PDF? 回答1: You can format the bounding box as follows figure(1) hold on; plot(1,1,'x') ps = get(gcf, 'Position'); ratio = (ps(4)-ps(2)) / (ps(3)-ps(1)) paperWidth = 10; paperHeight = paperWidth*ratio; set(gcf, 'paperunits', 'centimeters'); set

Comparison with NaN using AVX

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I am trying to create a fast decoder for BPSK using the AVX intrinsics of Intel. I have a set of complex numbers that are represented as interleaved floats, but due to the BPSK modulation only the real part (or the even indexed floats) are needed. Every float x is mapped to 0 , when x < 0 and to 1 if x >= 0 . This is accomplished using the following routine: static inline void normalize_bpsk_constellation_points(int32_t *out, const complex_t *in, size_t num) { static const __m256 _min_mask = _mm256_set1_ps(-1.0); static const __m256 _max
