根据运行的进程的名称杀死进程 ps -ef | grep 要杀掉的进程名称 | grep -v grep | awk ‘{print $2}’ | xargs kill -9 如： 有一个进程，我们不知道它的进程号，只知道他的进程名称是 config-center-1.0.0.5.jar ps -ef | grep config-center-1.0.0.5.jar | grep -v grep | awk ‘{print $2}’ | xargs kill -9 来源： CSDN 作者： 遇水则生 链接： https://blog.csdn.net/xiaojuge/article/details/103977281

Ubuntu系统下USB转串口的使用

由 房东的猫 提交于 2020-01-14 20:09:56
PC系统是Ubuntu12.04，与路由器开发板之间用USB转串口线连接。 一、硬件连接 确认Ubuntu对USB转串口设备的支持。 1、# lsmod | grep usbserial 如果有usbserial，说明系统支持USB转串口。 zlf@zlf:~$ lsmod |grep usbserial usbserial 39125 3 ftdi_sio 2、插上USB转串口，在终端输入命令 # dmesg | grep ttyUSB0 ，如果出现连接成功信息，则说明ubuntu系统已经识别该设备了。 zlf@zlf:~$ dmesg | grep tty [ 0.000000] console [tty0] enabled [ 1.854936] 0000:00:03.3: ttyS4 at I/O 0x1830 (irq = 17, base_baud = 115200) is a 16550A [ 920.550979] usb 6-1: FTDI USB Serial Device converter now attached to ttyUSB0 二、软件选用 这里使用minicom，一款linux系统下的串口通信软件，全键盘操作，用用就习惯了。 minicom的安装、配置可以参考这篇： ubuntu下的usb转串口的使用 。 来源： https://www

grep + grep + sed = sed: no input files

问题 Can anybody help me please? grep " 287 " file.txt | grep "HI" | sed -i 's/HIS/HID/g' sed: no input files Tried also xargs grep " 287 " file.txt | grep HI | xargs sed -i 's/HIS/HID/g' sed: invalid option -- '6' This works fine grep " 287 " file.txt | grep HI 回答1: If you want to keep your pipeline: f=file.txt tmp=$(mktemp) grep " 287 " "$f" | grep "HI" | sed 's/HIS/HID/g' > "$tmp" && mv "$tmp" "$f" Or, simplify: sed -i -n '/ 287 / {/HI/ s/HIS/HID/p}' file.txt That will filter out any line that

R: enumerate column combinations of a matrix

问题 (edit note: I changed the Title to "R: enumerate column combinations of a matrix", from "R grep: matching a matrix of strings to a list" to better reflect the solution) I am trying to match a matrix of strings to a list: so that i can ultimately use the matrix as a map in later operations on a data.frame . This first part works as intended, returning a list of all the possible pairs, triples and quad combinations (though perhaps this approach has created my bind?): priceList <- data.frame(aaa

Grep ambiguity nested square bracket

问题 sample.txt contains abcde abde Can anybody explain the output of following commands - grep '[[ab]]' sample.txt - no output grep '[ab[]]' sample.txt - no output grep '[ab[]' sample.txt - output is abcde , abde grep '[ab]]' sample.txt - no output And what does [(ab)] and [^(ab)] mean? Is it the same as [ab] and [^ab] ? 回答1: First thing to understand is, inside a character class, none of the meta-characters of regex has any special meaning. They are matched literally. For e.g., an * will match a

Cucumber: pipe output without losing color

由 余生长醉 提交于 2020-01-14 10:08:34
问题 I'm using cucumber to run some tests. It colorizes its output using ANSI escapes. This is great, but currently its producing more output than I care about, and shoving things I do care about off the screen. There doesn't seem to be a way to eliminate the other lines from within cucumber, but I can pipe the output through grep to pare down to the ones I care about. The downside of this solution, though, is that all the colors are lost. I know it's not my shell or grep's fault, because % echo "
