小编fri*_*dle的帖子

我只是尝试为我的Android手机编写一个bash shell.
当我想列出我的Android手机中的所有文件.我发现Android shell终端不支持find命令.
所以我只想知道哪个是旅行sdcard文件的最佳方式？

我的网络应用程序在晚上运行工作!并且遇到问题!它使用了大量内存!
我用命令查找占用java资源的函数!
结果是:

        [tomcat@uhzd006525 ~]$ jstack 2365 |grep 93f -A 30

我有以下问题

这是文字:

printf("sysname %s",ut.sysname);

我想用vim sysname逐行替换.我在我的gvim中输入命令:

:s/sysname/version

我想得到这样的输出:

printf("version %s",ut.version);

但我得到这样的输出:

printf("version %s",ut.sysname);

我究竟做错了什么？
