There is a limit (RE_DUP_MAX ) to the repetition. In some sed's this seems to be rather low (255 or so). BSD sed does not cut it, GNU sed does..

$ sed 's/.\{320\}/&\
/g' infile
sed: 1:...

Use fold instead:
fold -c320 infile > outfile

@sea: IFS can be used local to the read command:
while IFS=\| read ColA ColB ColC ColD
do
...
done < file
So IFS does not need to be set and reset..
Note that ColA is empty, ColD contains...

If your using gnu awk you have @include:

@include "foo.awk"
{ print add($1, $2) }

If your grep supports -o, that's another option:

$ grep -o "<a href[^>]*>" file
<a href='/misdownload/servlets/mirDownload?mimicKey=&doclookupId=317626164'>

while(<DATA>){
s/(?:[\[\]]|'(?=[^\[]*\]))//xg;
print;
}
__DATA__
"['1235','3234']","abcde","[1234]","['1235','3234']"
"'","abcde","[1235]","['1236','2234']"...

If you have some options that take option arguments and some that don't, you'll find that getopts gives you lots of capabilities that the type of script provided in message #2 in this thread does not...

Actually the quotes are not necessary for the assignment:
value=$(cat file1.txt)


--
or if it is always just one line:
read value < file1.txt

or

IFS= read -r value < file1.txt
to...

Some versions of awk provide a asort() and asorti() functions to sort data.
This example uses the sort utility to sort data and should work whether or not your version of awk has those functions. ...

Thanks alister...

Another factor that might prove an important factor is which awk or which grep is used.
For example when using the same extended regex ^83 *(1[0-9][0-9][0-9]|2000)$
I got the...

That's a reasonable assumption, but it turns out to be incorrect (at least with the implementation I tested).

In my testing, the following code is over three times faster than the original...

awk '{ORS=(ORS==RS)?FS:RS; print $NF}' infile

Hi.

An alternate with sed , cut , paste:
#!/usr/bin/env bash

# @(#) s1 Demonstrate combine lines fro specific column (field).

pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() {...

awk -F\; 'END {
for ( m = 0; ++m <= 3; )
printf "%s", h[m] FS
print "PARAM_HEADER", "PARAM_VALUE"
for ( j = 3; ++j < n; )
for ( i = 1; ++i <= NR; ) {
split( d[i], t )

Dear Forum Members,

awk does not print, because tail -f does not terminate, so awk clings to its buffers. Unfortunately, buffer control is not standard in awk. When using gawk, you can use fflush("") after a print...

Another option would be to use quotemeta i.e.

my $userInput = "[latency][info] mpgw(BLUESOAPFramework";
$userInput = quotemeta($userInput);

print "trans usrInput: $userInput\n";
if ( $str =~...

awk '/days_of_week/ && /start_times/ && !/date_conditions/{print $2}' RS= infile

Klashxx's result is correct. However, a more efficient way of calculating the result would be:
awk -v n=100 'BEGIN {while ((j=++i^2) <= n) print j}'

;)

If you think about the problem (forget...
