This is a port of GNU Sed 4.5 to MSDOS/DJGPP.
sed is a stream editor. A stream editor is used to perform basic text
transformations on an input stream (a file or input from a pipeline).
While in some ways similar to an editor which permits scripted edits
(such as ed), sed works by making only one pass over the input(s), and
is consequently more efficient. But it is sed's ability to filter text
in a pipeline which particularly distinguishes it from other types of
editors.
Please, read carefully the NEWS file to see the user visible changes
and read the info or html docs to become familiar with the program.
For beginers the chapter: examples in the info doc may be instructive.
The chapter: Other resources for learning about 'sed' contains pointers
to usefull sed specific urls.
DJGPP specific changes.
=======================
- There are no DJGPP specific user visible changes. Major adjustments
were required to get the new and even more posix centric testsuite
working with MSDOS/DJGPP.
- The port has been configured and compiled on WinXP SP3 and Win98SE.
There is no guarantee that this may be possible with any other DOS-
like OS. Due to the use of long file names it will not be possible
to configure and compile without LFN support. The port has been
compiled using gcc346 and bnu230b.
- The port has been tested by using it. I have used them only on WinXP.
It has worked flawlessly. I do not konw if this will ever be the case
on FreeDOS. I have never used/tested them in that environment.
- To be able to build this port you may need to have LFN support.
- If NLS support is wanted, then the sources must be reconfigured passing
the nls option to config.bat.
As usual, all djgpp specific files (diffs, README files, etc.) are stored
in the "djgpp" directory. The sources have been configured to be build
in the "_build" directory. If for some reason it does not work for you,
delete it contents and configure from scratch again.
Please read the docs to become familiar with this product.
Here is an extract of the NEWS file showing the user visible changes
from the last port (GNU Sed 4.4) to this one:
-------------------------------------------------------------------------------
* Noteworthy changes in release 4.5 (2018-03-31) [stable]
** Bug fixes
sed now fails when matching very long input lines (>2GB).
Before, sed would silently ignore the regex without indicating an
error. [Bug present at least since sed-3.02]
sed no longer rejects comments and closing braces after y/// commands.
[Bug existed at least since sed-3.02]
sed -E --posix no longer ignores special meaning of '+','?','|' .
[Bug introduced in the original implementation of --posix option in
v4.1a-5-gba68fb4]
sed -i now creates selinux context based on the context of the symlink
instead of the symlink target. [Bug present since at least sed-4.2]
sed -i --follow-symlinks remains unchanged.
sed now treats the sequence '\x5c' (ASCII 92, backslash) as literal
backslash character, not as an escape prefix character.
[Bug present since sed-3.02.80]
Old behavior:
$ echo z | sed -E 's/(z)/\x5c1/' # identical to 's/(z)/\1/'
z
New behavior:
$ echo z | sed -E 's/(z)/\x5c1/'
\1
