Delete a pattern including any whitespace before it and after it
Hello.
will remove 'SOME_WORD' and give :
A_PATTERN="SOME_WORD[[:space:]]"
will remove 'SOME_WORD' and the space after it and give :
Now the question
--------------------------
My problem is that the pattern is at the beginning of the line
I would like to remove the whitespace before and after it.
I tried this :
A_PATTERN="[[:space:]]SOME_WORD[[:space:]]"
should remove 'SOME_WORD' and the space before and after it.
But it does not work.
The pattern is at the beginning of the line and have white space after it.
But may or may not have white space before it.
ps (I made a try on a file where the pattern start at the beginning of the line without white space before it.)
@Aia: the problem with your approach is that
- either ALL multiple spaces in the string are reduced to a single one (if unquoted)
- or the spaces around A_PATTERN are preserved (if quoted), which was not what the OP requested.
