This is the start but i have problem on duplicate data, does anyone have any idea regarding it

BEGIN { FS=OFS="^" }
{
arr[$1] = ($1 in arr) ? arr[$1] "," $2 : $2
arr2[$1] = ($1 in arr2)...

I post my question here also because i have a difficult script to create that do the following:

The examples i got dont support it.
Lets say the input file is:
ABC^1^~^data^x
ABC^2^~^data^x...

Lets say the input file is:
ABC^1^~^data^x
ABC^2^~^data^x
ABC^3^~^data^x
DEF^4^~^data^y
DEF^4^~^data^z
DEF^5^~^data^y
DEF^5^~^data^z
DEF^6^~^data^z
DEF^6^~^data^y
XYZ^7^~^data^t

Now I...

you are the best

where the delimiter is ^ and if the concatenated field is not last.

Any idea ?

My file looks like:

X^~^12^d
X^~^19^d
Y^~^5^d
Y^~^10^d
Y^~^11^d
Z^~^14^d

I need a script that will "group by" the first field and Concatenate the values.

My output should be:
...

what is with the fgrep? will run faster?

I am working on solaris machine.

Can I change the e-mail in From: header

Currently it sends e-mail From: dev1@domain.com

Thanks in advance.

Thank you

Hi folks,

My input file's content:
You are line1
You are line2
You are line3
etc...


I need to write a script that for every line, it will send an e-mail and the body will hold the line:
...

I find this very helpful and hope that other people like me can use it on the future.

question:

I have about 150 files to process every night.
The size of each file can be between 5Mb to 20Mb.

What is more efficient to use?

thanks you all guys, you are great and I like this...

I call to your script runIt
I replace file1 with $1

Now I run it:
runIt file1

Output:

I get file2 with the correct lines, but they are all in lowercase.

I look at the unix console and...

Input file:

line 1: David, password: ab4TkN
line 2: Kevin, password: kRq5
line 3: kevin, PASSWORD: kRq5
line 4: abcd
line 5: efgh
line 6: ABCD
line 7: efgh

Output file:
line 1: David,...

Your script is great but it doesn't answer my question.

I need to keep the exact uniq content I have in the original file:
(suppose That each line has a pssword which is case sensetive)

So if...

file1 contain:
danIel
Kevin
DON
KEVIN
don

If I run your command as the following :
cat file1 | tr "[a-z]" "[A-Z]" | sort -u >outputFile
outPutFile contain:
DANIEL
DON
KEVIN

And this...

Because then I will lose the real values in the original file and the data I will get will be like converted (from lower to upper or and vice versia), because the input in file can be for example:...

hi,

I have the following input in file:
abc
ab
a
AB
b
c
a
C
B
When I use uniq -u file,the out put file is:
abc
ab
AB
c
v
B
C

Thanks, works like magic.
