sorts file with a sort key that starts with the 1st character on each line and continues to the end of the line. What was requested was:
Code:
sort -k1.1,1.6 file
which sorts with a key being the 1st six characters of the 1st field on each line.
But, since we aren't doing a numeric sort and we aren't performing a reverse order sort, both of the above, and the simpler:
Code:
sort file
will all do exactly the same thing.

Hi Don,
thanks,, what will ahppen if it s numeric..i tried to search in ggoogle..couldnt find exact answer
Code:
001asa003 hekk
100hasa341 no more
100asa012 try a d g
002asa001 a
039asa111 this is just a sample for long string
101sdfc
099sdfs
999
1441
102
1000
the always output no matter what kind of sort is
001asa003 hekk
002asa001 a
039asa111 this is just a sample for long string
099sdfs
1000
100asa012 try a d g
100hasa341 no more

Instead of searching Google for answers about how a utility works, try reading the man page for that utility on your system. In this case try the command:
Code:
man sort
to see the man page for the sort utility on your system. The behavior of lots of utilities varies from system to system. What you find on Google MIGHT or MIGHT NOT explain how the utility you're searching for will work on your system; the man page on your system WILL explain how the utility will work on your system.
If the man page on your system doesn't answer your question, or you don't understand what some of the words on the man page on you system mean; create a sample data file and try sorting with sort file (which your man page will explain performs an alphanumeric sort) and sort -n file (which your man page will explain performs a numeric sort). For example, if file contains:
Code:
sa003 hekk
ASA341 no more
asa012 try a d g
ASA001 a
asa111 this is just a sample for long string
000aaa note that a numeric sort treats sort keys starting with text as zero.
000AAA NOTE THAT A NUMERIC SORT TREATS SORT KEYS STARTING WITH TEXT AS ZERO.
001asa003 hekk
100hasa341 no more
100asa012 try a d g
002asa001 a
039asa111 this is just a sample for long string
101sdfc
099sdfs
999
1441
102
1000
then an alphanumeric sort (sort file) produces:
Code:
000AAA NOTE THAT A NUMERIC SORT TREATS SORT KEYS STARTING WITH TEXT AS ZERO.
000aaa note that a numeric sort treats sort keys starting with text as zero.
001asa003 hekk
002asa001 a
039asa111 this is just a sample for long string
099sdfs
1000
100asa012 try a d g
100hasa341 no more
101sdfc
102
1441
999
ASA001 a
ASA341 no more
asa012 try a d g
asa111 this is just a sample for long string
sa003 hekk
while a numeric sort (sort -n file) produces:
Code:
000AAA NOTE THAT A NUMERIC SORT TREATS SORT KEYS STARTING WITH TEXT AS ZERO.
000aaa note that a numeric sort treats sort keys starting with text as zero.
ASA001 a
ASA341 no more
asa012 try a d g
asa111 this is just a sample for long string
sa003 hekk
001asa003 hekk
002asa001 a

099sdfs
100asa012 try a d g

If you can't figure out why your examples aren't working the way you think they should, show us the sample input you used, the output you got, the code you used to transform that sample input to the output you got, show us the output you wanted to get (or expected to get), and explain what you didn't understand on the man page or what you were trying to do that didn't work.
We will be happy to help you figure out how to use the tools available on your system; we will quickly get tired of being asked to do someone else's work for them if they don't seem to be interested in learning how to do it on their own.

Hi,
I often need to find the child processes of a parent process. There may be a string of 4-5. That is, PPID 884 spawns 890, which spawns 894, which spawns 1017. I'd like to be able to see all of them without having to type in a number of ps -ef commands.
Process groups and session ID's are... (2 Replies)
This is a follow-up re: this thread
As I mentioned, this script works very nicely, thanks again.
However, the ASCII data of the 'attached file' also shows below the body of the email message. Do you know of a way to 'disable' the attached text from showing? Although the file is attached,... (3 Replies)
