Ok mogoce sm se mal prehitro zaletel, rabis se sed.. :)
Iz sedfaq:

 # 5. Delete leading whitespace (spaces/tabs) from front of each line
# (this aligns all text flush left). '^t' represents a true tab
# character. Under bash or tcsh, press Ctrl-V then Ctrl-I.
sed 's/^[ ^t]*//' file

# 6. Delete trailing whitespace (spaces/tabs) from end of each line
sed 's/[ ^t]*$//' file               # see note on '^t', above

# 7. Delete BOTH leading and trailing whitespace from each line
sed 's/^[ ^t]*//;s/[ ^]*$//' file    # see note on '^t', above


Za vrstice dat v eno pa uporabis tr:

tr -d \\012 


Btw: lahko bi se najprej mal naucil prebrat razne FAQ, in MAN page, in potem
spraseval, ne pa da je treba vse na pladnu prinest... (ne mislim tebe Andrej..)
