SED TIPS

In order to replace a word with a newline and some other text:
```
1,$s/Mode/Mode,\\^MUpdateMinMaxDb=1, OverWrite=1, HxRG=SHxRG/g
```
where Mode is the word you want to replace. To get the ^M, hold down Ctrl-V and press m

To replace a set of characters with the same characters (along with additional ones):
```
1,$s/Mode[...]/&/g
```
where Mode and the three charcters following it is the expression you want to replace. & will contain Mode+the 3 additional characters that follow it.

To replace a random number with itself (for instance, if you're searching for an expression with the number, but only want to change the characters around it):
```
1,$s/A\([0-9]\)/B\1/g
```
The previous syntax will replace occurence of A0, A1, A2, etc. with B0, B1, B2, etc. The \1 refers to the match to the expression in ()'s.

To replace the first character in each line with 2 spaces:
```
1,$s/^/ \ / 
```
If more spaces are desired, one can add that number of '\ ' after the last '\ ' in the line.

To replace the last character on a line with "LL":
```
1,$s/.\{1}$/LL/g
```
If more spaces are desired, one can add that number of '\ ' after the last '\ ' in the line.

To insert '||' at column 33:
```
1,$s/^(.\{33\}\)/\1||/g
```
The \(...\)) indicates this is a group.
The group consists of 33 instances (\{33\}) of any character (.) starting at the beginning of the line (^).
The (\1) replaces the group with itself.
SED does not recognize '\t' so use an actual stroke of the TAB key instead
