Lab 6.3. Using wc (Word Count): find + wc vs one line wc

lurodrig

Hello there,

For this lab I came out with a (ugly) solution like this:

$ sudo find /var/log/ -maxdepth 1 -type f -name *.log -exec cat '{}' > lab-6.3.tmp \;
$ cat lab-6.3.tmp | wc
 173745 1813744 21688868
$ rm -f lab-6.3.tmp

Which in theory should give the same results as the proposed solution, but:

$ sudo wc /var/log/*.log
     305     4964    73172 /var/log/alternatives.log
      10      126     1130 /var/log/apport.log

Any thoughts on this?

Thank you in advance,

Luis

ps: I've checked and both set of files should be the same for both solutions:

$ sudo find /var/log/ -maxdepth 1 -type f -name *.log | sort > find.out
$ ls /var/log/*.log | sort > ls.out
$ diff find.out ls.out
