Git diff: ignore lines starting with a word
As I have learned here, we can tell git diff
to ignore lines starting with a *
using:
git diff -G '^[[:space:]]*[^[:space:]*]'
How do I tell git to ignore lines starting with a word, or more (for example: * Generated at
), not just a character?
This file shall be ignored, it contains only trivial changes:
- * Generated at 2018-11-21
+ * Generated at 2018-11-23
This file shall NOT be ignored, it contains NOT only trivial changes:
- * Generated at 2018-11-21
+ * Generated at 2018-11-23
+ * This line is important! Although it starts with a *
regex git git-diff

Considering you are ignoring changes that does NOT match your regex, you just have to put the words you want inside the expression within a lookahead capture group, like this:
git diff -G '^(?=.*Generated at)[[:space:]]*[^[:space:]*]'
Note that if you want to keep adding words to ignore, just keep adding these groups (don't forget the .*
):
However, if the string contains a "Generated at" anywhere in their whole, it shall be ignored. If you want to define exactly how it should start, then replace the .
with a [^[:word:]]
.
git diff -G '^(?=[^[:word:]]*Generated at)[[:space:]]*[^[:space:]*]'
You can have a look at it's behaviour at
Version 1: .*

Version 2: [^[:word:]]*

Thanks for your answer. However, git version 2.7.4 seems not to support this regex, I am gettingfatal: invalid regex: Invalid preceding regular expression

Git is using POSIX regular expressions which seem not to support lookarounds. That is the reason why @Myys 3's approach does not work. A not so elegant workaround could be something like this:
git diff -G '^s*([^s*]|*s*[^sG]|*sG[^e]|*sGe[^n]|*sGen[^e]|*sGene[^r]|*sGener[^a]|*sGenera[^t]|*sGenerat[^e]|*sGenerate[^d]).*'
This will filter out all changes starting with "* Generated
".
