md5sum a directory

Generate:

find (your-dir) -type f -print0 | xargs -0 md5sum >> (output-md5sume-file)

Verify:

md5sum -c (output-md5sum-file)

my example:

robert@robert-desktop ~/work/nbd-work/ttt $ ls

first second test

robert@robert-desktop ~/work/nbd-work/ttt $ find -type f -print0 | xargs -0 md5sum >> ~/Test/mydir.md5

robert@robert-desktop ~/work/nbd-work/ttt $ cat ~/Test/mydir.md5

robert@robert-desktop ~/work/nbd-work/ttt $ md5sum -c ~/Test/mydir.md5

./second: OK

./first: OK

./test: OK

robert@robert-desktop ~/work/nbd-work/ttt $ echo $?

Use djgpp to build a DOS program in dosemu (under Linux)

Topic: How to use djgpp to build a DOS program in DOSEmu (running in Linux) ?

1. Install dosemu

DOSEmu (dosemu HOWTO)

2. Download djgpp files for dosemu

DJGPP (this name comes from ... DJ's GNU Programming Platform)

Use DJGPP Zip File Picker to download what you need (select dosemu for Operating System)

3. Install djgpp into dosemu

Refer to "installation instructions for dosemu" shown in DJGPP Zip File Picker Results. Key points:

* unzip those *.zip files to ~/djgpp/ (~ is your home in Linux)

* edit ~/.dosemu/drvie_c/autoexec.bat :

set PATH=d:\djgpp\BIN;%PATH%

set DJGPP=d:\djgpp\DJGPP.ENV

(dosemu defaults D:\ to ~/)

* reboot dosemu

4. Compile a helloworld in dosemu

* Edit main.c and its Makefile in ~/helloworld/ under Linux

* Then in dosbox, cd D:\helloworld\ and try to make it !

(gcc -o helloworld.exe main.c)

stop on first error (gcc, make)

Just want to see the first compilation error ? Try this:

-> gcc main.c -Wfatal-errors

-Wfatal-errors

This option causes the compiler to abort compilation on the first

error occurred rather than trying to keep going and printing

further error messages.

man gcc
