How to sed chunks text from a stream of files from find












2















I have a directory of many *.org files. I want to select a section of text out of all these org files.
There is a * Learnings header in the content. I would like to select from the * Learnings header to the end of the file.



My current attempt is



find ~/org/journal -name "*.org" -type f | xargs sed -n -e '/* Learnings/,$p'


This however just outputs one concatenated stream.



Expected output would be a stream of the content after the * Learnings header for each file returned from the find



also the solution does not have to use sed






sed find xargs

In Perl, you can use eof that will be true for each end of file:



find . -type f -name '*.org' -exec perl -ne 'print if /* Learnings/ .. eof' {} +


Using the + form of -exec works similarly to xargs: it builds the arguments to the specified command by appending all the found files.

    With the GNU implementation of sed, you can use the -s aka --separate option for each file to be treated separately in that regard.



    find . -name '*.org' -type f -exec sed -s '/* Learnings/,$!d' {} +


    With awk:



    find . -name '*.org' -type f -exec awk '
    
  FNR == 1 {found = 0}; /* Learnings/ {found = 1}; found' {} +

      Unless this is some kind of homework ;-), you can use the same trick as here with GNU or *BSD grep:



      grep -hrFA 10000 '* Learnings' directory


      Replace 10000 with something bigger if your files have more than 10000 lines.
