Re: Need refinement to minimal-bash-script

problems@gmail <problems@gmail>:
With previous help from contributors to this group, I've got
a script which reads the URLs from a file and dumps/appends
the [lynx] contents to a file, for reading off-line.
Here's the script-line which has been working well:
#
#!/bin/bash
for url in `cat NewsLst`; do lynx -dump "$url" >> accumNewsLst; done

So now I want to avoid having to add the URL as a header and
a "<><><>..." as a end-marker for each fetch which is appended to
the accumulating-file. Here's my failed attempt:

for url in `cat urls.txt`; do
echo "<><><><><>" >> accumulation;
"$url" >> accumulation;
echo " == blank line ==" >> accumulation;
lynx -dump "$url" >> accumulation; done

for url in `cat urls.txt`; do
echo >> accumulation # bare echo == newline
echo "$url" >> accumulation # added "echo"
echo >> accumulation
lynx -dump "$url" >> accumulation
echo >> accumulation
echo '<><><><><>' >> accumulation # single ticks.
done

BTW, bash also has printf, which may help consolidate the mess.

printf '\n%s\n' $url >> accumulation

replaces the first three echos.
