Eclipse - How to replace/delete lines

I am using eclipse v4.4.2 Text file contents have these lines:-

tosh1
tosh2
tosh3
tosh4
tosh4
tosh5

I am trying to match tosh4 and remove the lines. The regex ^\s+tosh4.*$ is returning with "String Not found"

Eclipse Search/Replace dialog I am not seeing what is wrong with the regex. Please help. Thx.

Lets dissect your regex:

^    fine: start of line
\s+  wrong: 1 or more SPACES
tosh4

tosh1 tosh2 tosh3 are for sure not spaces. That is why already the beginning of your regex can match!

what should work better

^.*tosh4.*$

Matching any line that contains tosh4. But as you are looking for a regular expression that get matching lines deleted, we have to enhance that to:

^.*tosh4.*\R

\R matches "new line" for all kinds of "new lines", no matter if \r\n Windows, or \n Linux, ... !

And for further reference: study the eclipse regex help pages, for example this here.
