The System V version of pr ( 43.7 ) has a -F option for folding lines that are too wide for the output page: the printer won't truncate them. If you print lots of random data and stuff that may have long lines and your pr doesn't have -F , try the fold command instead.
fold arbitrarily breaks lines that are too long, by default at 80 columns. Use - width where width is the desired column to fold at for some other breaking point.
I made an
alias (
10.2
)
and
shell function (
10.9
)
called
prF
to do that. It prints a single file and puts the filename in the
pr
heading (usually, if you pipe to
pr
, it won't know the filename). You might want to add
|
lpr
onto the end of this, too:
alias prF 'fold \!^ | pr -h "\!^"'
csh_init
sh_init |
A good way to see which lines are folded is with line numbering. pr versions without -F usually don't have -n either. You can add it to your alias with cat -n ( 25.21 ) . The lines will be numbered before they're folded: |
---|
alias prnF 'cat -n \!^ | fold | pr -h "\!^"'
To shorten lines by folding them after a word near the right-hand end (instead of at some particluar column), try fmt ( 35.2 ) .
