This might work:
echo 'His phone number is (123) 456-7890 and account is 34567 887272. ' | awk '
{while (match ($0, /[0-9()-]+ *[0-9()-]*/)) {X = substr ($0, RSTART, RLENGTH-4)
...

It's slightly more complicated than that - look at the sample input/output examples.

this is a bit convoluted - others might find a better, more generic approach - this is brute-force:

$ echo 'His phone number is (123) 456-7890 and account is 34567 887272. ' | \
awk '

Ok... so in general we have an old SysV vs. Berkley... or perhaps a ksh vs. Berkley-ism.

I too was somewhat displeased with the Linux choice of a BSD-ish like echo since it tried to be more POSIX...

Use ksh instead bash. You are probably used to ksh anyway when you come from AIX and it is available on every Linux since some time now. When using ksh you have the shell-internal "print" for output....

Try adding a newline before and/or after the --boundary line.

awk '/SNAPSHOT/{print ++c". The snapshot "$2" is created by volume: "$3;}' filename

#!/bin/bash

transpose()
{
awk '
{
if(max_nf<NF)
max_nf=NF
max_nr=NR
for(x=1; x<=NF; ++x)

The problem is that you aren't setting the value of FS until _after_ the first record has already been read and split. That first line is being split on whitespace. Since there is none, $3 is empty....

two points -

I disagree with in2nix.
find's behavior is largely very consistent, expecially on versions of UNIX that are POSIX-compliant.

find uses the stat() system call. This returns...

Sure OMLEELA,

I'll try to explain good enough :D

I'm using gensub function with regexp back reference feature, This feature within gensub works something like this:

gensub(/regexp/,...

Through sed..
grep 'number wasnt' logfile.txt |head -2| sed "s/^.*(\([^)]*\)).*(....\(.*\)).*'\(.*\)'.*/\1 \2 \3/"

This syntax is legal and it should work fine in ksh, bash, or even the old Bourne shell.

$ export ROWSTOLOAD=${ROWSTOLOAD:--100}

A race condition would be like, if they were trying to both write to the same file on disk simultaneously. Process 1 writes "hello", process 2 writes "world", you could get "helloworld",...

It depends on what the scripts are doing. If you have multiple scripts running at the same time and working with and modifying the same resources, you will likely experience unpredictable behavior...
