Top Forums Shell Programming and Scripting Grep command to ignore line starting with hyphen Post 302947556 by Srinraj Rao on Thursday 18th of June 2015 07:10:28 PM

Thanks for your quick response. My requirement is different.

The file contains text as follows.
Code:
#test
+abc
-xyz
real

The for loop has to read the file line by line and pass the string in each line to the do loop. While reading each line in the file, if the line starts with # or + or - that line should be ignored.
