Top Forums UNIX for Beginners Questions & Answers Date from filename inserted into records Post 302975886 by spirospap on Monday 20th of June 2016 06:14:03 PM

Honestly, I didn't but I found a perl one-liner to recursively delete the unnecessary lines before running the script you suggested
Code:
perl -i -pe "chomp if eof” */*

Now I am trying to substitute - with -9, decimals in form .x into 0.x and negative decimals such as -.x into -0.x
For example:
Code:
 
   020  1751           1.7
   020  1851           1.7
   020  1951           1.1
   020  2051            .6
   020  2151             -
   020  2251             -
   020  2351             -
   021  0051           -.6
   021  0151          -1.1

should end up like this
Code:
 
   020  1751           1.7
   020  1851           1.7
   020  1951           1.1
   020  2051           0.6
   020  2151          -9.0
   020  2251          -9.0
   020  2351          -9.0
   021  0051          -0.6
   021  0151          -1.1

Any suggestions would be greatly appreciated.

Thanks
