Is this the bid’s intent? If not, is equal accurate to usage it to accomplish this?

git rev-parse is an ancillary plumbing bid chiefly utilized for manipulation.

1 communal utilization of git rev-parse is to mark the SHA1 hashes fixed a revision specifier. Successful summation, it has assorted choices to format this output specified arsenic --abbreviated for printing a shorter alone SHA1.

Location are another usage circumstances arsenic fine (successful scripts and another instruments constructed connected apical of git) that I’ve utilized for:

• --confirm to confirm that the specified entity is a legitimate git entity.
• --git-dir for displaying the abs/comparative way of the .git listing.
• Checking if you’re presently inside a repository utilizing --is-wrong-git-dir oregon inside a activity-actor utilizing --is-wrong-activity-actor
• Checking if the repo is a naked utilizing --is-naked-repository
• Printing SHA1 hashes of branches (--branches), tags (--tags) and the refs tin besides beryllium filtered based mostly connected the distant (utilizing --distant)
• --parse-decide to normalize arguments successful a book (benignant of akin to getopt) and mark an output drawstring that tin beryllium utilized with eval

Therapeutic massage conscionable implies that it is imaginable to person the information from 1 signifier into different i.e. a translation bid. These are any speedy examples I tin deliberation of:

• a subdivision oregon tag sanction into the perpetrate’s SHA1 it is pointing to truthful that it tin beryllium handed to a plumbing bid which lone accepts SHA1 values for the perpetrate.
• a revision scope A..B for git log oregon git diff into the equal arguments for the underlying plumbing bid arsenic B ^A
