Can you please explain the code that you provided. And how i can implement the same in my scenario?

---------- Post updated at 01:59 AM ---------- Previous update was at 01:49 AM ----------

The below command is useful but it aslo delete the other patterns starting with AAABCDE

Code:

 
sed -e "s/|AAA[ ]*[^|]*|/|/g"

Sample :

Code:

|ABC ABC XHAMK|AAA  (0) 111-111-111, AAA, BB|ABS ABS XYZ|
|ABC BBB CCC|AAACDE|NNN XXX|...

Output: Bu using sed -e "s/|AAA[ ]*[^|]*|/|/g"

Code:

 
|ABC ABC XHAMK|ABS ABS XYZ|
|ABC BBB CCC||NNN XXX|...

Here, even the string AAACDE is getting deleted , which is incorrect.

Desired Output :

Code:

|ABC ABC XHAMK|ABS ABS XYZ|
|ABC BBB CCC|AAACDE|NNN XXX|..

Only Pattern starting with AAA followed with one or more space.
Logic: Read the pipe "|" followed with pattern (|AAA (One or more space) till the other pipe is encounter and replace with the "|")

replace(1)							  MySQL database							replace(1)

NAME

       replace	-  A utility program that is used by msql2mysql, but that has more general applicability as well. replace changes strings in place
       in files or on the standard input. Uses a finite state machine to match longer strings first. Can be used to swap strings.

USAGE

       replace [-?svIV] from to from to ... -- [files]

       or

       replace [-?svIV] from to from to ... < fromfile > tofile

SYNOPSIS

       replace [-?|-I] [-s] [-v]

DESCRIPTION

       replace

       -?|-I  info

       -s     silent

       -v     verbose

EXTRA INFO

       Special characters in from string:

       ^     Match start of line.

       $     Match end of line.

            Match space-character, start of line or end of line. For a end  the next replace starts locking at the end space-character.  A	
	      alone in a string matches only a space-character.

EXAMPLE

       this command swaps a and b in the given files:

       shell> replace a b b a -- file1 file2 ...
