Hi everybody I have a bunch of directories where somewhere in the path exists ONE and only one directory with a certain Name so the whole path would look something like .*/Name/.*. Unfortunately I do not know how many directories will precede /Name/ so all I can do is to check for the number of dirs following /Name/ Now I want to find all strings (as delivered by find) / directories ending in Name/one_dir_only .*/Name will also not be acceptable, as it is not followed by a subdir.
So of the following list I would like to extract those marked with a * * blaba/Name/aaa : ending in /Name/whatsoever with no further / blaba/Name/aaa/1 : Names/aaa/1 does not fit the pattern : 1 dir too many blaba/name/aaa/2 : as does aaa/2 : same * blaba/Name/bb : ending in /Name/whatsoever with no further / blaba/Name/bb/3 : /3 unwanted blaba/Name/Ccccc/5 : /5 unwanted * blaba/Name/Cc&DD : ending in /Name/whatsoever with no further / blaba/Name/Cc&DD/2 : /2 unwanted (find might deliver ./blabla/.... but that's includes in .*/Name/) so an easy regex would be .*/Name/[^/][^/]* for "easy" regex or .*/Name/[^/]+ for extended regex read .* : lets start with whatsoever /Name/ : followed by (verbatim) /Name/ (/is no special character in regexes) [^/][^]* : followed by anything except '/' with a length of at least 1 (first [^/]) So I put the above list into a file called x x : blaba/Name/aaa blaba/Name/aaa/1 blaba/name/aaa/2 blaba/Name/bb blaba/Name/bb/3 blaba/Name/Ccccc/5 blaba/Name/Cc&DD blaba/Name/Cc&DD/2 but cat x | grep '/Name/[^/][^/]*' yields blaba/Name/aaa blaba/Name/aaa/1 : _/_1 not in regex, strange blaba/Name/bb blaba/Name/bb/3 : _/_3 not in regex, strange blaba/Name/Ccccc/5 : _/_5 not in regex, strange blaba/Name/Cc&DD blaba/Name/Cc&DD/2 : _/_2 not in regex, strange however and quite strangely cat x | grep '/Name/[^/][^/]*$' as well as cat x | grep '^.*/Name/[^/][^/]*$' deliver the correct result, namely blaba/Name/aaa blaba/Name/bb blaba/Name/Cc&DD but what does $ (EOL) have to do with it. Looks like a bug in grep. The same sad result also comes from sed cat x | sed -ne '/.*\/Names\/[^/][^/]*/p' cat x | sed -ne '/.*\/Names\/[^/][^/]*$/p' # with EOL cat x | sed -ne '/.*\/Names\/[^/]\+/p' # with + (masked) cat x | sed -ne '/\/Names\/[^/]\+/p' # prefix omitted all yield blaba/Names/aaa blaba/Names/aaa/1 blaba/names/aaa/2 blaba/Names/bb blaba/Names/bb/3 blaba/Names/Ccccc/5 blaba/Names/Cc&DD blaba/Names/Cc&DD/2 i. e., the whole list, altho no / may follow the /Name/. Maybe somebody can shed some light on this murky matter.
