问题 I have been struggling trying to find a pattern with sed and then append a character on AIX. I have absolutely no problem on Linux, but I really don't get how it is supposed to work on AIX. Very simple : I have a /tmp/test.txt : 1 2 3 4 5 And I want : 1 2 10 3 4 5 So that I can understand how it works on AIX. On Linux, I can do sed -i '/2/ a 10\' /tmp/test.txt It works. On AIX, I know we have to do a work around because there's no -i. But even after looking at other topics like Find pattern

问题 I'm running two processes on AIX. Process one is generating several files, process two does backups from all files that are in a backup directory. Process one will copy or move the files into the backup directory. Since process two is always running in the background there is the risk of it starting a backup of a file that is still in the process of being copied or moved and therefore incomplete. How can I avoid this problem? 回答1: Process one should create files in another directory (on the

问题 Are there in AIX mechanisms EPOLL(Linux2.6)/KQUEUE(FreeBSD)/IO Completion Port(Windows) or their equivalents? And what kind of mechanisms are optimal for AIO on AIX for a large number of network connections? For example according to the Benchmarks, the mechanisms KQUEUE / EPOLL much faster than SELECT. http://libevent.org/ 回答1: I believe poll set is the best choice today. There is also the iocp interfaces which comes from windows. And there are the aio interfaces which use iocp under the

问题 I have a cron job which runs every 30 minutes to generate log files with time-stamp like this: test20130215100531.log, test20130215102031.log I would like to create one folder daily with date time-stamp and push log files in to respective date folder when generated. I need to achieve this on AIX server with bash. 回答1: Maybe you are looking for a script like this: #!/bin/bash shopt -s nullglob # This line is so that it does not complain when no logfiles are found for filename in test*.log; do
