yes, But I'm afraid to say that for numbers greater than 10000 this logic may not work out.

Hello,

I need to format a number..like 12900 should be printed as 12,900
and 1209 as 1,209 and so on. (Just like we do in excel).

Can this be done in awk. any printf options we have?Please...

Radouluv,

Can u explain this to me....

$acr = 'I LOVE INDIA';
$acr1 = join '', $acr =~ /\b\w/g;
print $acr1;

Thanks everyone, All your replies have been really helpful!

Thanks Matrixmadhan, Its workin fine!

$var1="LEN";
$VAR2="CODLENTT";


now, var2 contains var1(LEN).How do i check this in perl....
whether one string is a part of another..?

if (<logic>)
{
my operation;
}

what'd be the...

ILN is gettin printed on the console....I dont need that

String1 has "I LOVE INDIA"
I want the operation to be performed on string1(the variable) and at the end of it string2 should have ILN

...

I need the perl solution for the following :

$string="I LOVE INDIA"


now, in a new string i need the first character of each word...

that is string2 should be "ILN".

Thats nice Pludi. But I'd prefer that to be done in shell itself
not possible with shell command,awk or sed?

I have a file with the following contents..say

123 abc 90and /[abd] 1009

from which i only need numbers to be printed.
like 123 90 1009

using any shell command.

Thanks.

Thanks Whiteboard n gaurvacl...
that works absolutely fine...great!

are u sure..?

grep -vf file1 file2 does not work as intended.somother solution,please.

for ex: the contents of fileA is
A
B
C

and that of fileB is

A
C

now,diff fileA fileB

would give

2d1
< B

as the output

But i need only the difference not the line info ....

Wat does this command do?

fileA is a subset of fileB..now, i need to find the lines in fileB that are not in fileA...i.e fileA - fileB.

diff fileA fileB gives the ouput but the format looks no...

Thanks franklin,your post was helpful

Salil,

123 123 234 678 269 1 2 3 4 1

The above line should be processed by the AWK, as all the fields only have numericals values....


whereas the line

123 123 s 678 269 1 a3 4 1
...

I need to check all fields in a line contain only numbers....

for ex....
echo "123 123 234 678 269 1 2 3 4 1" | awk '{for(i=1;i<=NF;i++){<ur logic>}}'


The command should be processed as...

is there any operator like

<<$a>> in csh or ksh...?

for ex...

echo "<<$a>>";

what does this do...?

can we use |(pipe operator) with find -exec.....?

or can pipe the output of find command to another command...?

if not, why...?

pls explain

Actually its enough if the value satisfies..REG_EXP of


^([[:alpha:]]+[.]? )+(#|# |NO |NO. )?[[:digit:]]

But since it takes much time ...I thought of adding (A){0,1}...wich obviously does not...

I need to select all those values with....



REGEXP_INSTR(column_name,'^((A){0,1}[[:alpha:]]+[. | ]?)+[[:digit:]]+[-|/]?[[:digit:]]*$') = 0





But with " ^((A){0,1} " at the begining...

In VI editor ctrl + g is used indicate the line number on which the cursor is placed...similarly is there a way to determine the column number of the cursor position..?

basename $a

try this....tell me if this works fine.....

awk '{
if(NR%3!=0)
{
print
}
else
{
for(i=1;i<=NF;i++)
{
if(i==1)
{
printf("%s ",substr($1,2,length($1)-1))
}
else
{
printf("%s ",$i)
}...

try this...

echo e1000g0 | sed 's/[0-9]$//g'
