%general-entities; ]> Ed The Ed package contains a spartan line editor. &buildtime; 0.1 SBU &diskspace; 3.1 MB Ed installation depends on: Bash, Binutils, Coreutils, Diffutils, GCC, Glibc, Grep, Make, Sed. 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 ). Apply the following patch to make Ed use mkstemp instead, a secure way to create temporary files: patch -Np1 -i ../ed-&ed-version;-mkstemp.patch Now prepare Ed for compilation: ./configure --prefix=/usr --exec-prefix="" The meaning of the configure option: --exec-prefix="": This forces the programs to be installed into the /bin directory. Having the programs available there is useful in the event of the /usr partition being unavailable. Compile the package: make To test the results, issue: make check. Install the package: make install Installed programs: ed and red (link to ed) ed ed is a line-oriented text editor. It can be used to create, display, modify and otherwise manipulate text files. red red is a restricted ed -- it can only edit files in the current directory and cannot execute shell commands.
