EDTF - IBM Edit File Utility
The Edit File (EDTF) command allows you to edit an (IFS) stream file or a database file. This command can also be used to browse a file or directory. EDTF is not a code editor tool, think of its a basic NOTEPAD style editor. It offers no syntax checking.
If SEU is not accessible you can use the EDTF command to edit from any command line:
In an emergency, EDTF is a useful alternative to DFU for quick minor code changes in IBM i Source Code:
Example 1: Editing a Stream File
EDTF STMF('/mydir/myfile.txt')
Example 2: Editing a Database File Member
EDTF FILE(MYLIB/MYFILE) MBR(MYMBR1)
