什么是AIX下的AIX上的'what'命令

Question

I am used to use what to find out some version string in my program, which is normal defined as a string in the c++ code, starting with "@(#)".

Now I cannot find it in Linux. Can anyone tell me what I am supposed to do? Thanks a lot!

Answer 1

The what command is part of the Source Code Control System (SCCS), which is not commonly available on Linux (if there is a Linux version at all). You can try to emulate it with the strings command:

strings a.out | fgrep '@(#)'

Reimplementations of what are available in CSSC (an SCCS-to-modern version control conversion package) and in BSD ( source code ).

Answer 2

试试这个

strings myprogram | grep '@('

Answer 3

As @larsmans said, what command is part of SCCS . Here is the link to the GNU replacement for SCCS

Answer 4

The following command gives most equivalent output compared to what
strings filename | grep -o \\"\\"@(#).*\\"\\" | sed 's/^\\"@(#)//' | sed 's/\\"$//'

Answer 5

除了提到SCCS之外， ident也是RCS的等价物（并且有很多工具使用与RCS相同的标记，CVS是其中的第一个）。
