内核中实际执行execv()或execve()系统调用的程序是do_execve(),这个函数先打开目标映像文件,并从目标文件的头部(第一个字节开始)读入若干(当前Linux内核中是128)字节(实际上就是填充ELF文件头,下面的分析可以看到),然后调用另一个函数search_binary_handler(),在此函数里面,它会搜索我们上面提到的Linux支持的可执行...
users can search a file for aspecific pattern of characters or simply text. This Linux command will display all lines in a file matching the given pattern or text. We term this pattern searched in the file as the regular expression.
find . -type f -name "*.java" -exec grep -l StringBuffer {} \; # find StringBuffer in all *.java files find . -type f -name "*.java" -exec grep -il string {} \; # ignore case with -i option find . -type f -name "*.gz" -exec zgrep 'GET /foo' {} \; # search ...

The point where the kernel starts its first user-space process, init, is significant—not just because that’s where the memory and CPU are finally ready for normal system operation, but because that’s where you can see how the rest of the system builds up as a whole. Prior to this ...
grep (缩写来自Globally search a Regular Expression and Print,即正则表达式的全局搜索和打印输出)是一种强大的文本搜索工具,它能使用特定模式匹配(包括正则表达式)搜索文本,并默认输出匹配行。Unix的grep家族包括grep、egrep和fgrep。 1.1 语法 基本用法: grep -options(参数) pattern(关键词) files(文本文件) 全部...

Since an exact match is required, if you want to use this form for symbolic modes, you may have to specify a rather complex mode string. For example `-perm g=w' will only match files which have mode 0020 (that is, ones for which group write permission is the only permission set). ...
