The March 2003
Linux Magazine
Power Tools column,
Transfer Tips, Part I,
needs these corrections:
Page 46 (first page of article), right-hand column, fourth paragraph:
"by, escaping" should be "by escaping".
Page 47 (second page of article), left-hand column, first and second
examples: the ls -F output should be on two lines, with
bin/ on the first line of output and xfr/ on the
second. This is because the ls utility only outputs
filenames in columns (more than one filename per line) if its
standard output is a tty device.
When ssh runs ls on a remote host, there's no
tty on that host -- so ls outputs one name per line.
Page 47 (second page of article), left-hand column, last line:
The command line is missing the greater-than sign (>).
It should read:
% ssh bar 'ls -F > bar-ls'
Note: Page 48 (third page of article) shows how to compress data streams.
Your system's scp and ssh programs
may accept a -C (uppercase letter C) option, which does
basically the same thing -- if the remote server supports it.
The April 2003 column explains -C.
Note: Page 49 (fourth page of article), the section "X Tunnels
Through ssh": If your system's ssh program
accept the -C (uppercase letter C) option, you can
compress the X data stream. This is a great way to run X over
dialup connections.
The April 2003 column explains -C.
Page 49 (fourth page of article), the examples at the bottom
of the left-hand column and top of the right-hand column:
when you run ssh in the background -- as we do here,
with the ampersand (&) operator -- you may need
to use the ssh-n option. This keeps the
background job from hanging with the message (from your shell):
"Stopped (tty input) ssh...".
Page 49 (fourth page of article), last paragraph:
the next column, April 2003, doesn't cover rsync,
as this paragraph says it would.
We moved rsync to the May column.
The April column covers ftp and wget.
Page 49 (fourth page of article), bottom of right column,
last line of Power Tip: the ps command is missing
its -p option. It might also be a good idea to
put quotes around the grep search pattern.
The alias should be:
