Hello All,
I am stuck with a regular expression and I would appreciate your help. I want to list some specific cases from some simulations. For instance, I have the following case names:
...
wkxr4_75_ind1_350_0.inf
wkxr4_75_ind4_400_0.inf
swxr4_75_ind3_420_0.inf
wkxr4_75_cap1_350_0.inf
stxr4_75_cap2_400_0.inf
wkxr4_75_cap5_420_0.inf
...
Until now I just needed to do something simple, like getting the cases that started with sw, or wk, or st:
^(sw|wk|st)
However, now I want to find of those cases, the ones that also contain 400_0 and 420_0
I undertand the $ character can be used to give me the end, and it could work with something like this, right?
$(400_0.inf|420_0.inf)
The complete expression would be something like this below. However, I tried several different variations without success. For instance using [a-z_]+. etc.
'^(sw|wk|st) 'something here?' $(400_0.inf|420_0.inf)'
Thanks in advance!
Best regards,
Adriel Perez

I recommend that site when building regular expressions.
^(sw|wk|st).+(400_0\.inf|420_0\.inf)$
% ^ start ^^ ^ ^ ^
% ^^ ^ ^ ^ end
% ^^ anything in between
% ^ .........^ escape characters (\) for decimal points

Another way to write the end of that regular expression would be:
'^(sw|wk|st).+4[02]0_0\.inf$'
And the .+ could be .* depending on whether or not you want something between the two expressions.
