Finding a text in files & replacing it with unique strings
Hallo Everyone.
I have to admit I'm shell scripting illiterate . I need to find certain strings in several text files and replace each of the string by unique & corresponding text.
I prepared a csv file with 3 columns: <filename>;<old_pattern>;<new_pattern>
A very kind guy (much more skilled than me) helped me with the script:
To find & replace text I run the script and grep:
With the above file.csv example the script works fine and do what's intended. The problem starts if <old_pattern> and <new_pattern> text have white spaces:
In that case script returns errors.I tried to modify file.csv by putting text between quotation marks but it didn't help. How the script should be adjusted to work with text consisting of white spaces? I would appreciate any help from you. Thank you very much in advance. Regards,
gordom

diff3
diff3(1) General Commands Manual diff3(1)Name
diff3 - 3-way differential file comparison
Syntax
diff3 [-ex3] file1 file2 file3
Description
The command compares three versions of a file, and publishes the ranges of text that disagree, flagged with the following codes:
==== all three files differ
====1 file1 is different
====2 file2 is different
====3 file3 is different
The type of change needed to convert a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c
Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Options-3 Produces an editor script containing the changes between file1 and file2 that are to be incorporated into file3.
-e Produces an editor script containing the changes between file2 and file3 that are to be incorporated into file1.
-x Produces an editor script containing the changes among all three files.
Examples
Under the -e option, publishes a script for the editor that incorporates into file1 all changes between file2 and file3 - that is, the
changes that would normally be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ==== (====3).
The following command applies the resulting script to `file1':
(cat script; echo '1,$p') | ed - file1
Restrictions
Text lines that consist of a single `.' defeat -e.
