SSH asking every single time for passphrase

由 ＊爱你＆永不变心＊ 提交于 2019-12-09 14:00:36
问题 I have an annoying problem with my private key. Every time I want to clone or push via ssh in terminal or Tower app, I have to type my passphrase. I even removed and recreated the ssh key and set the key on Github several times, but it looks like it has a short lifetime and after a couple of minutes, is expired! I followed generate a new SSH key to create the key. At the end I ran ssh-add ~/.ssh/id_rsa and it printed out: Identity added: /Users/sajad/.ssh/id_rsa (/Users/sajad/.ssh/id_rsa)

erasing terminal output on linux

由 孤街醉人 提交于 2019-12-09 10:55:25
问题 I was writing a command line program which will have a status bar, much like wget. The main problem I'm facing is: how do I delete what I've already sent into stdout/stderr? I had on idea: use the backspace char '\b' and erase the output I've sent. Is that the best way? Is it the only way? Is there a better way? PS: I don't want to use anything like ncurses. Plain old C please. Thanks EDIT: Can I also go up and/or down? Example: I have 10 lines of output, I want to change the 3rd line from

由 放肆的年华 提交于 2019-12-09 04:36:33
I am setting up the CLI on a MAC (iOS 10.9) and I believe I've set up the MTURK_CMD_HOME and JAVA_CMD_HOME paths correctly. But, I'm still getting an error that the file can't be found when I run getBalance.sh .

Version control Word .docx files with docx2txt with Git on Mac OS X

由 一曲冷凌霜 提交于 2019-12-09 04:18:41
问题 On Git web site there is a detailed instruction for version controling Microsoft Word .doc files with catdoc . http://git-scm.com/book/en/Customizing-Git-Git-Attributes However, I realized that this doesn't work for .docx files. It seems that you need either docx2txt or unoconv instead of catdoc (found here). I decided to go with docx2txt for no reason, but I was stuck at the installation of docx2txt into Mac OS X. This sort of illustrates the steps. In my understanding, all you need is

Mac OS X shell utility that shows individual cpu usage in multi-core systems

由 ﹥＞﹥吖頭↗ 提交于 2019-12-09 02:39:54
问题 I've been looking for a osx utility that shows cpu usage for each cpu. For example CPU 0 - 10% CPU 1 - 2% ... I know of many ways of getting this information in other Unix-like system (/proc, mpstat, etc) but none work in osx. The most useful one for Mac is top but it only shows total cpu usage. I need the application to be run from the shell so that I can log the usage over time. I also tried cpuwalk.d but it only shows you if the application is running in one or more cores. If you take a
