Hi,
Being a slow Perl learner who hasn't make much progress, I'm wondering
if some kind souls could help me achieve the following 2 text
substitution tasks detailed below.
********substitution 1************
The characteristic of original string:
1, always start with "$"
2, then followed by an integer, could be more than 1 digit, such as 23
3, always end with a period "."
4, there is always a blank before & after original string
For example: $2.
The characteristic of target string: always has "ebcdic" inserted into
the original string between "$" and the integer
For example: $ebcdic2.
So the substitution will look like this
$2. -> $ebcdic2.
$67. -> $ebcdic67.
Should the regular expression for original string be: \$\d+\. ?
********substitution 2************
The characteristic of original string:
1, always start with an integer, could be more than 1 digit, such as 23
2, then end with a period "."
3, there is always a blank before & after original string
For example: 2.
The characteristic of target string:
always has "s370ff" added to the beginning of original string
For example: s370ff2.
So the substitution will look like this
2. -> s370ff2.
14. -> s370ff14.
Should the regular expression for original string be: \d+\. ?
My real situation is that I have a bunch of files at one directory, of
which for the files whose name contained "readme", I need to do 2
substitutions described above.
Any input (and your time) is greatly appreciated.
Thanks,
Zhao
