my use case want search collection of jars specific class file. more specifically, want search recursively within directory *.jar files, list contents, looking specific class file. so have far: find . -name *.jar -type f -exec echo {} \; -exec jar tf {} \; this list contents of jar files found recursively. want put grep within seconed exec because want second exec print contents of jar grep matches. if put pipe , pipe grep afterward, like: find . -name *.jar -type f -exec echo {} \; -exec jar tf {} \; | grep $classname then lose output of first exec , tells me class file (the name of jar file not match class file name). so if there way exec run 2 commands, like: -exec "jar tf {} | grep $classname" \; then work. using grep $(...) in exec command wouldn't work because need {} find take place of file found. is possible? ( also open other ways of doing this, command line preferred. ) i find difficult execute multiple commands within
