I have long sed substitution expressions in a bash script.
I don't particularly like having such long lines, is it possible to have them split on several lines, i.e.
sed -r -e 's/
match/
replacement/
options'
This would avoid ending up with lines that have 100+ characters, but i've never seen this before using sed.
Perl will let you do this - I recommend looking that up if it's an option -
but in sed you can still use a quoted line break, if perhaps not with the indentation.
sed -r -e 's/'\
'match/'\
'replacement/'\
'options'
In use:
$: echo this needs some match | sed -r -e 's/'\
> 'match/'\
> 'replacement/'\
> 'g'
this needs some replacement
