GNU ed is an 8-bit clean, POSIX-compliant line editor.
Installed programs: ed and red (link to ed)
Ed depends on: Bash, Binutils, Coreutils, Diffutils, GCC, Glibc, Grep, Make, Sed.
Note: Ed isn't something which many people use. It's installed here because it can be used by the patch program if you encounter an ed-based patch file. This happens rarely because diff-based patches are preferred these days.
Ed normally uses the mktemp function to create temporary files in /tmp, but this function contains a vulnerability (see the section on Temporary Files in http://en.tldp.org/HOWTO/Secure-Programs-HOWTO/avoid-race.html). The following patch makes Ed use mkstemp instead, which is the recommended way to create temporary files.
Apply the patch:
patch -Np1 -i ../ed-0.2-mkstemp.patch |
Now prepare Ed for compilation:
./configure --prefix=/usr |
Compile the package:
make |
This package has a test suite available which can perform a number of checks to ensure it built correctly. Should you choose to run it, the following command will do so:
make check |
Install the package:
make install |
And move the programs to the /bin directory, so they can be used in the event that the /usr partition is unavailable.
mv /usr/bin/{ed,red} /bin
