# [RFC/PATCH] git-show: also handle blobs 2 messages from 2006-12-03 to 2006-12-03. Participants: Johannes Schindelin, Jakub Narebski. Thread: https://gitlist.dev/t/43531 ## Johannes Schindelin, 2006-12-03 18:54 Subject: [RFC/PATCH] git-show: also handle blobs Message-ID: URL: https://gitlist.dev/e/Pine.LNX.4.63.0612031952050.28348%40wbgn013.biozentrum.uni-wuerzburg.de ``` Now you can say "git show v1.4.4.1:Makefile" and it pipes the requested contents into your favourite pager. While at it, the manpage for -show is updated; it no longer pipes anything, but rather uses the internal revision walking machinery. Better not mention it at all. Signed-off-by: Johannes Schindelin --- This combines the "wouldn't it be nice to have git-cat or git-less" wishes with "we do not want to clutter up the namespace any more. If people like this approach, we could easily enhance this patch to be a synonym for "-p cat-file -p" for _every_ non-commit on the command line.

But I agre that technical information should not be in DESCRIPTION section of manpage... perhaps later, if it is needed. -- Jakub Narebski Warsaw, Poland ShadeHawk on #git ```
