Using sed to edit multiple files
Created a shell script to invoke sed to edit multiple files, but am missing something.
Here's the shell script:
Code:
oracle:$ cat edit_scripts.sh
#!/bin/sh
#------------------------------------------------------------------------------
# edit_scripts.sh
#
# This script executes sed to make global edits to the template files
#------------------------------------------------------------------------------
for i in *.sh; do
  sed -f script.sed < $i
done
#
for i in *.sql; do
  sed -f script.sed < $i
done

As you can see, I'm using a script file 'script.sed' to supply the actual editing commands:
Code:
oracle:$ cat script.sed
s/@yymmdd@/181016/g
s/@gi patch num@/12345678/g
s/@jvm patch num@/87654321/g

And for testing purposes, I have one .sh script to be edited:
Code:
oracle:$ ll *.sh
-rwxr-x--- 1 oracle oinstall 359 Jan  3 14:30 edit_scripts.sh
-rw-r--r-- 1 oracle oinstall 163 Jan  3 14:46 sed_sample.sh

oracle:$ cat sed_sample.sh
#-------------------
#  This should be the date: @yymmdd@
#  This should be the gi patch num:  @gi patch num@
#  This should be the jvm patch num: @jvm patch num@

But when I execute edit_scripts.sh, sed_sample.sh is not modified:
Code:
oracle:$ ./edit_scripts.sh
#!/bin/sh
#------------------------------------------------------------------------------
# edit_scripts.sh
#
# This script executes sed to make global edits to the template files
#------------------------------------------------------------------------------
for i in *.sh; do
  sed -f script.sed < $i
done
#
for i in *.sql; do
  sed -f script.sed < $i
done
#-------------------
#  This should be the date: 181016
#  This should be the gi patch num:  12345678
#  This should be the jvm patch num: 87654321
./edit_scripts.sh: line 12: *.sql: No such file or directory

oracle:$ cat sed_sample.sh
#-------------------
#  This should be the date: @yymmdd@
#  This should be the gi patch num:  @gi patch num@
#  This should be the jvm patch num: @jvm patch num@

idle

IDLE(1) 						      General Commands Manual							   IDLE(1)

NAME

       IDLE - An Integrated DeveLopment Environment for Python

SYNTAX

       idle [ -dins ] [ -t title ] [ file ...]

       idle [ -dins ] [ -t title ] ( -c cmd | -r file ) [ arg ...]

       idle [ -dins ] [ -t title ] - [ arg ...]

DESCRIPTION

       This  manual page documents briefly the idle command.  This manual page was written for Debian because the original program does not have a
       manual page.  For more information, refer to IDLE's help menu.

       IDLE is an Integrated DeveLopment Environment for Python. IDLE is based on Tkinter, Python's bindings to the Tk widget  set.  Features  are
       100%  pure  Python, multi-windows with multiple undo and Python colorizing, a Python shell window subclass, a debugger. IDLE is cross-plat-
       form, i.e. it works on all platforms where Tk is installed.

OPTIONS

       -h     Print this help message and exit.

       -n     Run IDLE without a subprocess (see Help/IDLE Help for details).

       The following options will override the IDLE 'settings' configuration:

       -e     Open an edit window.

       -i     Open a shell window.

       The following options imply -i and will open a shell:

       -c cmd Run the command in a shell, or

       -r file
	      Run script from file.

       -d     Enable the debugger.

       -s     Run $IDLESTARTUP or $PYTHONSTARTUP before anything else.

       -t title
	      Set title of shell window.

       A default edit window will be bypassed when -c, -r, or - are used.

       [arg]* and [file]* are passed to the command (-c) or script (-r) in sys.argv[1:].

EXAMPLES

       idle   Open an edit window or shell depending on IDLE's configuration.

       idle foo.py foobar.py
	      Edit the files, also open a shell if configured to start with shell.

       idle -est "Baz" foo.py
	      Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell window with the title "Baz".

       idle -c "import sys; print sys.argv" "foo"
	      Open a shell window and run the command, passing "-c" in sys.argv[0] and "foo" in sys.argv[1].

       idle -d -s -r foo.py "Hello World"
	      Open a shell window, run a startup script, enable the debugger, and run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
	      sys.argv[1].

       echo "import sys; print sys.argv" | idle - "foobar"
	      Open a shell window, run the script piped in, passing '' in sys.argv[0] and "foobar" in sys.argv[1].
