git log --stat Recap

--stat is a flag

To recap, the --stat flag is used to alter how git log displays information:

$ git log --stat

$ git log 8d3ea36  --stat

This command:

• displays the file(s) that have been modified
• displays the number of lines that have been added/removed
• displays a summary line with the total number of modified files and lines that have been added/removed

git log -p Recap

To recap, the -p flag (which is the same as the --patch flag) is used to alter how git log displays information:

$ git log -p

This command adds the following to the default output:

• displays the files that have been modified
• displays the location of the lines that have been added/removed
• displays the actual changes that have been made

$ git log -p -w

With-w, don’t highlight lines where only whitespace changes occurred.

Annotated git log -p Output

git log -p or git log --patch

Using the image above, let’s do a quick recap of the git log -p output:

• 🔵 - the file that is being displayed
• 🔶 - the hash of the first version of the file and the hash of the second version of the file not usually important, so it’s safe to ignore
• ❤️ - the old version and current version of the file
• 🔍 - the lines where the file is added and how many lines there are
  • -15,83 indicates that the old version (represented by the -) started at line 15 and that the file had 83 lines
  • +15,85 indicates that the current version (represented by the +) starts at line 15 and that there are now 85 lines…these 85 lines are shown in the patch below
• ✏️ - the actual changes made in the commit
  • lines that are red and start with a minus (-) were in the original version of the file but have been removed by the commit
  • lines that are green and start with a plus (+) are new lines that have been added in the commit

git show

git show can be combined with most of the other flags we’ve looked at:

• --stat - to show the how many files were changed and the number of lines that were added/removed
• -p or --patch - this the default, but if --stat is used, the patch won’t display, so pass -p to add it again
• -w - to ignore changes to whitespace
