Extract a column and multiple by 1000 and replace it on same file
Hi All,
I need to extract a position in the file and multiple the value by 1000 and the replace it .
The problem is if I 055716 with 1000 will get 55716000.Since my layout can handle only 6 digit I should be able to store 557160. I am not able to fit this into. I am able to extract separate with awk but not able to fit in the file. Also I am not to convert the 55716000 this scenario in aw
Hello!
Is it anyone who might know how to extract the n last lines from a file, typically the 1000 last? Until know I have used sed -n np filename, but it takes each line separately, and is hence very time consuming.
Thank you in advance! (3 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 -d <object>...
git replace -l [<pattern>]
DESCRIPTION
Adds a replace reference in .git/refs/replace/
The name of the replace reference is the SHA1 of the object that is replaced. The content of the replace reference is the SHA1 of the
replacement object.
Unless -f is given, the replace reference must not yet exist in .git/refs/replace/ directory.
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For example if commit foo has been replaced by commit bar: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
If an existing replace ref for the same object exists, it will be overwritten (instead of failing).
-d
Delete existing replace refs for the given objects.
-l <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.
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. And of course things may break if an object of one type is
replaced by an object of another type (for example a blob replaced by a commit).
