Hi,
> ... ignoring both leading spaces and leading tabs. eg.
Something like (there must be nothing but tabulation before closing ``EOF'')?
func(){
sed 's/^ \{2\}//' <<- EOF
blabla
EOF
}
Depending on how and why, there is a lot of *variants*:
- leading spaces and/or/not leading tabs
- trailing spaces and/or/not trailing tabs
- keeping rest of line structure as is or replacing every number of
spaces/tabs by one space
- ...
Even merging lines like `xargs` does, there is a way I've used in some scripts,
( like https://f-hauri.ch/vrac/live-install.sh.txt ):
myXargs() { sed -ne '/#/d;s/ \t//g;H;${x;s/\n/ /g;s/^ //;p}'; }
This drop lines containing `#`, every spaces and merge all line as space
separated words. I use this as:
ExtraBootParams=$(myXargs <<-eobp
boot=live
config
# locales=de_CH
locales=fr_CH
keyboard-layouts=ch
keyboard-variant=fr
persistent=cryptsetup
persistence-encryption=luks
persistence
eobp
)
PackageList=$(myXargs <<-eopl
gnome
gnome-core
# gnome-full
# debian-forensics
debian-installer-launcher
eopl
)
