Combine multiple awk output to print on one line

阅读更多关于 Combine multiple awk output to print on one line

问题 I have two different functions I wrote, each with their own AWK to search for a specific file in multiple directories and output the information I need. Both functions print the FILENAME and a specific field I need and work just fine on their own. I want to combine them together for more robust output. I am not a programmer. I wrote these while reading about awk as I went. Function 1 cver () { X="" case $1 in ("-b") X="bb";; ("-c") X="cpe";; ("-e") X="etech";; ("-k") X="core";; ("-o") X=

Cucumber: pipe output without losing color

阅读更多关于 Cucumber: pipe output without losing color

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 "

How can I prompt for yes/no style confirmation in a zsh script?

阅读更多关于 How can I prompt for yes/no style confirmation in a zsh script?

问题 Using zsh, I'm trying to put a step in my ~/.zprofile where I interactively ask a yes/no style question. At first I tried this bash-style approach, but I saw errors of this form: read: -p: no coprocess (I'm aware that typically the zsh syntax is different from bash's - I tried preceding it with a sh emulation command - emulate -LR sh - but it made no difference). This page implied the syntax might be different, so guided by this page and the zsh man page, I tried this instead: read -q REPLY?

Opening a new terminal tab in OSX(Snow Leopard) with the opening terminal windows directory path

阅读更多关于 Opening a new terminal tab in OSX(Snow Leopard) with the opening terminal windows directory path

问题 I've been Googling for a while looking for a simple way to do this, and I can't find one. I have a custom terminal environment set up (zsh) with various aliases and functions to make things easier. One thing I keep running into is that I will quickly APPLE-t to create a new tab and then type a command relative to the path of the terminal window I was just in. This invariably fails because the path of the new tab is ~/ instead of whatever I was just using! Any ideas for a script to set the

Zshell starts up with exit status of 1 after uninstalling RVM

阅读更多关于 Zshell starts up with exit status of 1 after uninstalling RVM

问题 I've just uninstalled rvm—I ran rvm implode and removed rvm from $PATH in my .zshrc , as specified in this Stack Overflow post. Since uninstalling, I've noticed that my shell startup has an exit status of 1 . I've checked this by using echo $? after loading the shell—I always get 1 back. I briefly reinstalled rvm to confirm that's what caused the change, and sure enough, after reinstalling, my exit status was back to zero on startup. I've tried commenting out my zshell so that there's no

如何更改登录的shell

阅读更多关于如何更改登录的shell

1 我想知道我机器安装了哪些shell？两种方法可以查看：第一种： [rocrocket@wupengchong ~]$ chsh -l /bin/sh /bin/bash /sbin/nologin /bin/zsh 第二种： [rocrocket@wupengchong ~]$ cat /etc/shells /bin/sh /bin/bash /sbin/nologin /bin/zsh 其实chsh -l也是来查看这个文件。 2 我想知道我当前正在使用的shell是哪个阿？ [rocrocket@wupengchong ~]$ echo $SHELL /bin/bash 注意SHELL一定要是大写。可以看到，我目前使用的shell是/bin/bash 3 执行了zsh之后，我查看当前shell类型仍然是/bin/bash呢？请注意，我们虽然执行了zsh，但是所谓“当前的shell”是一个大环境的概念，是针对一个已登录的用户而言的。而我们执行zsh只是启动了一个zsh的解释器程序而已，并没有改变大环境。如果想改变“当前的shell”，那么还是要使用chsh才可以。 4 我想把我的shell改成zsh！ [rocrocket@wupengchong ~]$ chsh -s /bin/zsh Changing shell for rocrocket.
