A one-liner script for shell output redirection that inserts instead of appends Typically cat file2 >> file1 If want to place file2 at the top of file1 instead of the bottom cat file2 file1 > file3 mv file3 file1 Too much typing, margin for error The script is called "ins" ins file1 < file2 Can also use line number ins file1 25 < file2 Inserts file2 at line 25 of file1 One of the most useful scripts I have ever written Only uses sed or ed
