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@
