Usage: ./findversion.sh
|
|
Finds the current revision and if the code is modified.
|
|
|
|
Output: <VERSION>\t<ISODATE>\t<MODIFIED>\t<HASH>
|
|
VERSION
|
|
a string describing what version of the code the current checkout is
|
|
based on.
|
|
This also includes the commit date, an indication of whether the checkout
|
|
was modified and which branch was checked out. This value is not
|
|
guaranteed to be sortable, but is mainly meant for identifying the
|
|
revision and user display.
|
|
|
|
If no revision identifier could be found, this is left empty.
|
|
ISODATE
|
|
the commit date of the revision this checkout is based on.
|
|
The commit date may differ from the author date.
|
|
This can be used to decide upon the age of the source.
|
|
|
|
If no timestamp could be found, this is left empty.
|
|
MODIFIED
|
|
Whether (the src directory of) this checkout is modified or not. A
|
|
value of 0 means not modified, a value of 2 means it was modified.
|
|
|
|
A value of 1 means that the modified status is unknown, because this
|
|
is not an git checkout for example.
|
|
|
|
HASH
|
|
the git revision hash
|
|
|
|

|
|
version of "awk" is used. If nothing is set, this script defaults to
