why cant I redirect the output from sed to a file

由 隐身守侯 提交于 2021-02-20 18:51:12
问题 I am trying to run the following command ./someprogram | tee /dev/tty | sed 's/^.\{2\}//' > output_file But the file is always blank when I go to check it. If I remove > output_file from the end of the command, I am able to see the output from sed without any issues. Is there any way that I can redirect the output from sed in this command to a file? 回答1: Remove output-buffering from sed command using the -u flag and make sure what you want to log isn't on stderr -u, --unbuffered load minimal

Nodejs installed without npm?

由 ぐ巨炮叔叔 提交于 2021-02-18 11:16:09
问题 I've just installed nodejs on Debian 7 - by apt-get install nodejs. Nodejs seems to be working fine, but when I enter "npm" I get "command not found". "which nodejs" points to "usr/bin" and there it is - nodejs, but there is no npm file, what went wrong? I found a few solutions, but all of them are related to Macs BTW, "usr/local/bin" directory is empty I believe everything should install right there? 回答1: You have several options.

MySQL container crash after /etc/mysql/my.cnf change, how to edit back?

由 旧城冷巷雨未停 提交于 2021-02-17 05:27:29
问题 I changed some mysql config settings and set something wrong, now Docker container keeps restarting and I cannot find the my.cnf file to edit in host filesystem. I have tried aufs/diff folders but so far unable to find it. Also tried: find / -name my.cnf -exec nano {} \; But it does not bring up the file I changed. And I tried to change config.v2.json to start /bin/bash instead of mysqld and restarted docker, but yet it started mysqld (due supervisor or something?) using official mysql
