1 Download and install, or copy the git command line suite for MS-Windows
Topic:.git.cmd.install.
You can download a git suite for command line processing from https://git-scm.com/download/win and install it. The installed files run on an other computer without installing. That may be important if you have experience with several git installations.
I have installed Git-2.9.3.2-32.bit.exe
on a computer running under Windows-XP. I have answered all questions during the install process with the minimal influence to the operation system:
Select components: Deselect all! No icons, no Windows Explorer Integration, no change of file extension-associations.
No change of the system‘s PATH variable: Use Git from Git Bash only
Use OpenSSH
Configure the line ending conversions: Checkout as-is, commit-as-is: See TODO
Use MinTTY (the default terminal of MSYS2), don‘t select Use Windows‘ default console window
Enable file system chaching
I have select
D:\Programs\Gitcmd
as destination for installation. That is my tool folder.
This produces the following files (raw):
D:\Programs\Gitcmd>dir Directory of D:\Programs\Gitcmd29.08.2016 11:50 <DIR> .29.08.2016 11:50 <DIR> ..29.08.2016 11:38 <DIR> bin29.08.2016 11:38 <DIR> cmd29.08.2016 11:38 <DIR> dev29.08.2016 11:38 <DIR> etc25.08.2016 13:47 151.272 git-bash.exe25.08.2016 13:47 150.760 git-cmd.exe09.08.2016 19:02 18.765 LICENSE.txt29.08.2016 11:38 <DIR> mingw3225.08.2016 15:06 77.551 ReleaseNotes.html29.08.2016 11:38 <DIR> tmp29.08.2016 11:38 996.808 unins000.dat29.08.2016 11:34 1.293.032 unins000.exe29.08.2016 11:38 22.815 unins000.msg29.08.2016 11:38 <DIR> usr 7 File(s) 2.711.003 bytes 9 Dir(s) 83.736.236.032 bytes free
I have copied that file tree to a Windows-7-Computer, it runs perfect, without installation.
An older version of GitCmd gives the following files:
D:\Programs\Gitcmd_1608>dir Directory of D:\Programs\Gitcmd_160803.05.2015 13:29 <DIR> .03.05.2015 13:29 <DIR> ..25.08.2016 23:33 20 .bash_history31.07.2014 19:55 <DIR> bin31.07.2014 19:55 <DIR> cmd31.07.2014 19:55 <DIR> doc31.07.2014 19:55 <DIR> etc04.02.2014 17:27 793 Git Bash.lnk02.06.2013 12:30 708 Git Bash.vbs31.07.2014 19:55 <DIR> lib31.07.2014 19:55 <DIR> libexec02.06.2013 12:30 38.203 ReleaseNotes.rtf31.07.2014 19:56 <DIR> share31.07.2014 19:56 <DIR> ssl04.02.2014 17:26 566.105 unins000.dat04.02.2014 17:25 1.243.915 unins000.exe 6 File(s) 1.849.744 bytes 10 Dir(s) 83.732.533.248 bytes free
There are some other directories, mingw3w
is missing. Nevertheless it produces the adequate results. Both contains
D:\Programs\Gitcmd_1608\bin>dir sh.exe04.02.2014 17:27 540.672 sh.exeD:\Programs\Gitcmd\bin>dir sh.exe25.08.2016 13:47 43.240 sh.exe
There are some changes in the tool suite, but the behaviour for the usage is the same.
2 sh.exe
Topic:.git.cmd.sh.
The D:\Programs\Gitcmd
... \bin\sh.exe
is a windows program to run linux shell scripts or linux commands.
2.1 pure run >sh.exe
Topic:.git.cmd.sh.pure.
Without any other action, only invoked from a Windows command line (double click in explorer), it opens a linux-like command window. That shell window gets the environment variables from MS-Windows and sets the path variable (slightly) properly. One can type in some linux commands, here is an example content of the shell window after some commands:

The environment variables $HOMEDRIVE
and $HOMEPATH
are set in the windows environment. The $HOME
is set newly for this shell with the input of $HOMEDRIVE
and $HOMEPATH
. The $PATH
is set from the given path but enhanced with /mingw32/bin:/usr/bin
and change ;
to :
(Windows separator ;
versus Unix separator :
).
The root of the linux directory is built internally. The root is the parent directory from the bin\sh.exe
invocation. But the bin
itself where sh.exe
is stored is not member of. Instead usr\bin\
is mounted as bin/
which is in the path. Furthermore /c/
and /d/
are available which is the whole hard disk‘s content. /c/
and /d/
are not shown with the ls
command, but they are available though.
2.2 run sh.exe in a batch file with some environment variables
Topic:.git.cmd.sh.bat.
The HOMEDRIVE
and the HOMEPATH
environment variable may be other than for windows usage. Therefore they are set before, and then sh.exe
is called:
Content of unix_window.bat
:
@echo offset PATH=D:\Programs\Gitcmd\bin;%PATH%set HOMEPATH=\vishia\HOMEset HOMEDRIVE=D:::sh.exe --login -ish.exe
The PATH extension and the environment variables may be set in the Windows system environment in this kind already, but if they are set only in this batch, then its changed content is valid only for that session.
The variant with --login -i
came from an older git cmd tool suite (from 2010 I think), it has no effect for the newer one.
That batch creates a Unix/Linux shell window to have some experiences with Linux command line invocations.
2.3 run sh.exe in a batch file to execute one linux cmd, especially git with options
Topic:.git.cmd.sh.batcmd.
Content of unix_cmd.bat
:
@echo offset PATH=D:\Programs\Gitcmd\bin;%PATH%set HOMEPATH=\vishia\HOMEset HOMEDRIVE=D:REM The only one argument of this batch should be given with "" usual,REM because the argument of the batch is the command with arguments for sh.exe-execution.REM -x to output the command as they are executed.REM -c to run the following argument in "" as command, then exit.REM Write unix_cmd.bat "cmd arg1 ‘arg2 with spaces‘ arg3" for arguments with spaces.echo onsh.exe -x -c %1
This executes the given command by argument.
If that batch is invoked from another batch for example with a complex git command, one should regard some special rules for batch processing in windows.
Example content of a test-gitlog.bat:
unix_cmd.bat "git log --date=iso -z -b --ignore-space-change --no-textconv ‘--format=tformat:Commit::%%H %%h %%an %%ad %%+s‘ org/vishia/util/CalculatorExpr.java" >test.txt
The linux cmd should be written as one argument in "...." for the batch. The same rule is valid if sh.exe -c "command" will be invoked.
Note that the character %
should be written twice: %%
because the batch processing in windows detect that %
as expansion switch for environment variables. %%
expands to a single %
. The same rule is valid if sh.exe
was invoked immediately in a batch.
2.4 run sh.exe in a batch file to execute a shell script
Topic:.git.cmd.sh.batscript.
Content of unix_script.bat
:
@echo offset PATH=D:\Programs\Gitcmd\bin;%PATH%set HOMEPATH=\vishia\HOMEset HOMEDRIVE=D:REM -x to output the command as they are executed.echo onsh.exe -x %1
The sh.exe runs the given path/to/file
as a unix shell script and terminates then. The option -x
is proper to see which commands are executed in the script. It is adequate echo on
in windows. Adequate some echo ...
lines should be written in the script.
2.5 The sh.exe executes MS-Windows executables
Topic:.git.cmd.sh.exeWin.
In a shell script all windows executables can be invoked. Only the internal shell commands are linux-typical. If executables are equal for unix and windows you can use the same linux shell scripts for both platforms, maybe it is lesser effort for maintenance. Nevertheless some options are slightly different.
2.6 Run sh.exe from a Java application
Topic:.git.cmd.sh.java.
Java provides with the system‘s class javadoc-java/lang/ProcessBuilder the capability to run a opertion system process with a given executable. That works for MS-Windows, for Linux and all other platforms.
The class srcJava_vishiaBase/org/vishia/cmd/CmdExecuter builds a wrapper surround the java/lang/ProcessBuilder to help deal with input, output, abort, and several additional possibilities. That class is used to run sh.exe
respectively git
from a Java application: srcJava_vishiaGui/org/vishia/gitGui/GitGui.
CmdExecuter cmd = new CmdExecuter(); ..... void initializeCmd() { Map<String, String> env = cmd.environment(); env.put("HOMEPATH", "\\vishia\\HOME"); env.put("HOMEDRIVE", "D:"); String sPath = env.get("PATH"); sPath = "D:\\Programs\\Gitcmd\\bin;" + sPath; env.put("PATH", sPath); } ..... public void revisionsCommit(String sGitDir, String sFile) { cmd.setCurrentDir(new File(sGitDir)); out.buffer().setLength(0); out.assign(out.buffer()); //to reset positions to the changed out.buffer() String[] args ={"D:/Programs/Gitcmd/bin/sh.exe", "-x", "-c", "git log --date=iso ‘--pretty=raw‘ ‘" + sFile + "‘"}; int error = cmd.execute(args, null, out, null); out.firstlineMaxpart();
There are the adequate operations like in the MS-Windows-batches above. Only with Java syntax. The PATH enhancement is valid only for the running cmd, not for the start. Therefore the sh.exe
should be invoked with the full path. The special arguments should be taken from a config file, it is TODO yet.
3 git log
Topic:.git.cmd.log.
It offers a history of all commits, maybe for the whole repository, for some branches or especially for one file.
--pretty=format:%H %an %ad %+s
It seems to be a format in one line-thinking, proper for simply parsing algorithm for example with pearl text processing. Therefore the format flag ,%s
, writes the commit message in one line. All line-feed characters are replaces by spaces. That has the disadvantage that the originally commit message are garbled.
In conclusion the printf-like format is not able to use fortunately. I uses the --pretty=raw
format and parse it with a well Java parser srcJava_vishiaBase/org/vishia/util/StringPartScan.
It is in progress .... TODO
