We have a file (e.g. a .csv file, but could be any other format), with 2 columns: the old value and the new value. We need to modify all the files within the current directory (including subdirectories), so find and replace the contents found in the first column within the file, with the contents of the 2nd column
e.g. the file can contain:
COL1 -- COL2
That 'new_one' string can contain '!' or single quotation marks, which i should escape them. Is it possible this? To get the value in shell script, from the first column (so, read the csv line by line), and the new value from the second column.
If so, how?
