I was curious whether awk is a soft link to gawk on my Slackware systems so I checked. They are two separate binaries. Since awk is apparently not the same as gawk, what version of awk does it represent?
Are they separate binaries, or are they hard-linked (rather than symlinked)?
The file size will be exactly the same if they're hard-linked. On a CentOS 7 machine, for instance, unzip and zipinfo are actually the same binary:
[heinlein@hub bin]$ ls -l unzip zipinfo -rwxr-xr-x. 2 root root 181248 Feb 25 2015 unzip* -rwxr-xr-x. 2 root root 181248 Feb 25 2015 zipinfo* They both share the same inode: [heinlein@hub bin]$ stat -c '%i %N' unzip zipinfo 978894 ‘unzip’ 978894 ‘zipinfo’ If you look at the man page, you'll see it makes that clear.Otherwise, try 'awk --version' and 'gawk --version'. On my Mac, awk is the BSD version, while gawk is from GNU:
[client]$ awk --version awk version 20070501 [client]$ gawk --version GNU Awk 4.1.4, API: 1.1 -- Paul Heinlein <> [email protected] <> http://www.madboa.com/
