Search or grep docker logs

Normal grep and piping seems not to work for docker:


That is normal, because docker logs internally to the standard error out, so we have to redirect the standard error output (2) to the standard output (1):


Install error while installing ios-deploy globally on El Capitan

7zip process cannot access the file because it is being used by another process


I tried to compress a set of files via batch processing. Some of these files were currently opened by another process, so I encountered this problem.

7zip works as designed to skip those files, because an opened file could be uncompleted in the moment where we are trying to read it for compression, so its best practice to skip them.
