Thanks, gets me all the way! Have a great day.

Regarding copy/pasted text of copyright-free book from archive.org (link below), in attempt to expand single-line-break paragraph text (not section headings or paragraph breaks) to wider right...

Of course the files will be in folders. I just wanted all the downloaded folders in 1 directory, and that's not gonna happen, given that wget -O can't be piped to grep. wget and grep are working as...

Making, and cd'ing into all those nested directories is inefficient, when I might have all the URL folders in 1 directory.

Thanks for explanation; you'll see I did post that error message a few posts ago.

So I'll have to make a new directory every time I run this sequence...pretty inefficient. Anyhow if you or anyone...

That's interesting, thanks. Probably getting closer?

-k or -r can be used together with -O only if outputting to a regular file.

Just Googled fifo...this isn't doing anything differently than what I've already posted (no error either).

Hi, thanks for responding:
Linux Mint 18.1
GNU bash, version 4.3.46(1)-release (x86_64-pc-linux-gnu)

The results are identical in the example you suggested, no errors.

Hi, I need to join these statements for efficiency, and without having to make a new directory for each batch. I'm annotating commands below.
wget -q -r -l1 URL
^^ can't use -O - here and pipe |...

Thanks, both those commands hang/freeze in bash terminal, but they led to solving in 2-parts, which I'd like to consolidate into 1:

I need to extract text between numerous story-title=" "

I'm sorry, by modifying sed example I meant embedded in your example prints "an an hour." I understand why (2nd statement matching "(a)n" from 1st...so how to fix?
sed 's/^\<hour\>/an &/;...

Thanks rdrtx1, RudiC and R. Singh for awk and sed examples. Working great! The sed example puts letters in array and avoids overwriting by &/; which the awk example does by next.

Good point Don...

Prepending lines with: your, the, a or an based on 1st letter match. You'll see my problem below:
sed '/^p\|^f\|^c\|^d\|^l/ s/^/your /' list.txt > your.txt && sed '/^v\|^j\|^k\|^m\|^n\|^s/ s/^/the...

Thanks very much RudiC and R. Singh! In each example, seems either { } or 2 (second pattern) can be used to match h ref.

Thanks so much, R. Singh, indeed, that does it!

RudiC, following your example, I'd like to solve also with sed. I'm trying this and variations, which give blank file:
sed -n '/^<th.^<a...

Thanks RudiC, those are both very close. I probably should have posted table structure because the sed commands are returning some fields from other table elements. I just need the text in between...

I'm extracting text between table tags in HTML

Thanks for responses. After staring at the else statement for a few minutes and working out what was happening on a piece of paper, the concept became clear.

Referring to this:
#!/bin/awk -f

BEGIN{
for(i=0;i<=10;i++)
{
if (i <=1 )
{
x=0;
y=1;
print i;
}
else
{
z=x+y;
print z;
x=y;
y=z;
}
}

Thanks again RudiC, I understand now that loop is questionable for single value.

x=0
echo 'Enter number:'
read x
i=$((x*x)) #&& [ rem in $((((i % 2)) | bc)) ] # integer arithmetics.
echo...

Thanks for reply. Here is the working script. You can see commented section referenced in first post; I'd like to consolidate:
#!/bin/sh

x=0

echo 'Enter number:'
read x
for i in $((x*x)) ...

Bash shell, variables i and rem are working fine in 2 separate for loops, but I'd like to consolidate them like this:
for [ i in $((x*x)) ] && [ rem in $((((i % 2)) | bc)) ] This gives syntax...

Thanks very much Don. That's perfect; replaces this step I was doing:
awk '{$1=$1}1' in > left-trim
