I have text like these :
div class="ls-icon ls-item " data-ctrdot="214752854">
div class="ls-icon ls-item " data-ctrdot="213523235">
div class="ls-icon ls-item " data-ctrdot="788746365">
div class="ls-icon ls-item " data-ctrdot="332532436">
and i want to export :
data-ctrdot="214752854">
data-ctrdot="213523235">
data-ctrdot="788746365">
data-ctrdot="332532436">
but i dont know why this
grep -o 'data-ctrdot="\\w*'
does not work . Thanks
If by does not work you mean it outputs this:
data-ctrdot="214752854
data-ctrdot="213523235
data-ctrdot="788746365
data-ctrdot="332532436
Instead of
data-ctrdot="214752854">
data-ctrdot="213523235">
data-ctrdot="788746365">
data-ctrdot="332532436">
Then yes, it's broken. But perhaps you could just inject the last two characters into the grep expression?
grep -o 'data-ctrdot="\w*">'
data-ctrdot="214752854">
data-ctrdot="213523235">
data-ctrdot="788746365">
data-ctrdot="332532436">
您可以使用:
awk '/data-ctrdot=/{print $NF}' file
