Automating find and replace REGEX expressions in a script
I've made several REGEX expressions which I would like to use to find and replace text in a .srt file:
For example, below, the first is the pattern to be found. The second is the replacement. These work with my text editor just fine:
There are several more that I have, so I'd like to be able to throw them into a script which would read and replace each successively and for every instance in a given file.
Any idea of a program that could do this? I've had a look at SED, but it seems that using it might require a lot of extra work in editing the expressions.
Hi, I am trying something like this: Let's say I have a file called File1 with contents:
x=-0.3
y=2.1
z=9.0
I have another file, File2, with contents:
xx=
yy=
zz=
(nothing after "="). What I want to do is get the value of x in File1 and set it to xx in File2, i.e., xx=-0.3. And the... (3 Replies)
Hi,
I need to do an exact find and replace (I don't want to use regular expressions because the input comes from user). I want to find a line that matches the user's input text and replace it with an empty string.
For example, let's say the user enters I love "Unix" and the contents of the... (2 Replies)

git-replace
GIT-REPLACE(1) Git Manual GIT-REPLACE(1)NAME
git-replace - Create, list, delete refs to replace objects
SYNOPSIS
git replace [-f] <object> <replacement>
git replace [-f] --edit <object>
git replace [-f] --graft <commit> [<parent>...]
git replace -d <object>...
git replace [--format=<format>] [-l [<pattern>]]
DESCRIPTION
Adds a replace reference in refs/replace/ namespace.
The name of the replace reference is the SHA-1 of the object that is replaced. The content of the replace reference is the SHA-1 of the
replacement object.
The replaced object and the replacement object must be of the same type. This restriction can be bypassed using -f.
Unless -f is given, the replace reference must not yet exist.
There is no other restriction on the replaced and replacement objects. Merge commits can be replaced by non-merge commits and vice versa.
Replacement references will be used by default by all Git commands except those doing reachability traversal (prune, pack transfer and
fsck).
It is possible to disable use of replacement references for any command using the --no-replace-objects option just after git.
For example if commit foo has been replaced by commit bar:
$ git --no-replace-objects cat-file commit foo
shows information about commit foo, while:
$ git cat-file commit foo
shows information about commit bar.
The GIT_NO_REPLACE_OBJECTS environment variable can be set to achieve the same effect as the --no-replace-objects option.
OPTIONS-f, --force
If an existing replace ref for the same object exists, it will be overwritten (instead of failing).
-d, --delete
Delete existing replace refs for the given objects.
--edit <object>
Edit an object's content interactively. The existing content for <object> is pretty-printed into a temporary file, an editor is
launched on the file, and the result is parsed to create a new object of the same type as <object>. A replacement ref is then created
to replace <object> with the newly created object. See git-var(1) for details about how the editor will be chosen.
--raw
When editing, provide the raw object contents rather than pretty-printed ones. Currently this only affects trees, which will be shown
in their binary form. This is harder to work with, but can help when repairing a tree that is so corrupted it cannot be pretty-printed.
Note that you may need to configure your editor to cleanly read and write binary data.
--graft <commit> [<parent>...]
Create a graft commit. A new commit is created with the same content as <commit> except that its parents will be [<parent>...] instead
of <commit>'s parents. A replacement ref is then created to replace <commit> with the newly created commit. See
contrib/convert-grafts-to-replace-refs.sh for an example script based on this option that can convert grafts to replace refs.
-l <pattern>, --list <pattern>
List replace refs for objects that match the given pattern (or all if no pattern is given). Typing "git replace" without arguments,
also lists all replace refs.
--format=<format>
When listing, use the specified <format>, which can be one of short, medium and long. When omitted, the format defaults to short.
FORMATS
The following format are available:
o short: <replaced sha1>
o medium: <replaced sha1> -> <replacement sha1>
o long: <replaced sha1> (<replaced type>) -> <replacement sha1> (<replacement type>)
CREATING REPLACEMENT OBJECTSgit-filter-branch(1), git-hash-object(1) and git-rebase(1), among other git commands, can be used to create replacement objects from
existing objects. The --edit option can also be used with git replace to create a replacement object by editing an existing object.
If you want to replace many blobs, trees or commits that are part of a string of commits, you may just want to create a replacement string
of commits and then only replace the commit at the tip of the target string of commits with the commit at the tip of the replacement string
of commits.
BUGS
Comparing blobs or trees that have been replaced with those that replace them will not work properly. And using git reset --hard to go back
to a replaced commit will move the branch to the replacement commit instead of the replaced commit.
There may be other problems when using git rev-list related to pending objects.
