I have directory tree with many tar files. Each tar file contains many other files. I want to search through all the tar files for a given pattern, and print the full path of any files within a tar that are found.

I got this far: find . -type f -name '*.tar' -exec tar tf {} \; | egrep '<pattern>'

Now my problem is that the above command only prints the name of the file within the tar that it finds. Ie, the output of the above is:
pattern.jpg foundMe.txt

I would like the output to contain also the full path and the tar name where the file was found. How would I do this?

Thank you!

  • What is your pattern -- it is capturing only the filiename? For me find returns the full path relative to whence I'm executing the command by default.

  • Yes, find does do that, but then -exec tar tf only returns the name of the file within the tar archive Nov 10, 2014 at 12:28
  • Have you tried execdir? See this question.

  • that doesn't help, tar tf still only outputs the name of the file, I need to combine the tar file path from <find> command with result of <tar tf | egrep 'pattern'> Nov 10, 2014 at 13:31

Of course, lost the plot somewhere along the line :$

I had a similar problem with jar files, looking for java classes. Used to do something like this: capture the output of each tar tf|grep <pattern> then look see if the output contains a value - if so, print name ($f) and value ($p):

find . -name '*.tar' -type f|while read f; do p="$(tar tf $f|egrep <pattern>)"; [ -n "$p" ] && echo -e "$f\n$p" ; p=""; done

Switched the order of find arguments - cheaper to look at file name before file type.
