Writing Screen output to a file and emailing

vijayrc · 06-08-2009, 06:35 PM

Hi,

I have a file with the contents as follows

File_Name_Size.txt
1000 FileA
2000 FileB
3000 FileC

where the first field is the size of the file in bytes; while the second field is the filename.

when I do the following;
awk 'BEGIN {printf ("File Totals")}
{ total = total +1}
{printf "%20s,%9d\n", $2, $1 }
END {printf "%20s,%9d\n", "Total File size is " $total}
File_Name_Size.txt

I get the following:
File Totals
FileA 1000
FileB 2000
FileC 3000
Total File Size is 6000

I want this to be written to a file called File_Name_Size_Total.txt
I'm struggling to redirect the printf to this file w/ all syntax error. I'm a newbie and any help would be appreciated on modifying the existing awk statement to write to the file in the format I desire; or any other way to achieve this..

I tried the following:
echo `awk 'BEGIN {printf ("File Totals")}
{ total = total +1}
{printf "%20s,%9d\n", $2, $1 }
END {printf "%20s,%9d\n", "Total File size is " $total}
File_Name_Size.txt` >> File_Name_Size_Total.txt

Results are like this
File Totals FileA 1000 FileB 2000 FileC 3000 Total File Size is 6000

Thanks a bunch

Hi,

Welcome to LQ!

What about presenting the information or queries too your instructor?

Hi, welcome to LQ!

Your problem is that you're being too complicated :)

Give the echo a miss.

Code:

awk 'BEGIN {printf ("File Totals\n")} { total = total +1} {printf "%20s,%9d\n", $2, $1 } END {printf "%20s,%9d\n", "Total File size is " $total}' File_Name_Size.txt >> File_Name_Size_Total.txt

Cheers,
Tink

The illustration of my example might sound from a Linux class; but this is the scenario i am working at my workplace and needed some guidance.

Hi,

Sorry! I've seen that example many times. As 'Tink' stated, you do need to simplify.

I'll try this tomorrow..Thanks for your input.
So this is what I should try to get the output as I needed ?

awk 'BEGIN {printf ("File Totals")}
{ total = total +1}
{printf "%20s,%9d\n", $2, $1 }
END {printf "%20s,%9d\n", "Total File size is " $total}
File_Name_Size.txt >> File_Name_Size_Total.txt
File Totals
FileA 1000
FileB 2000
FileC 3000
Total File Size is 6000

A couple of minor mistkes in there, but yes, basically that's it.

File_Name_Size.txt >> File_Name_Size_Total.txt
File Totals
FileA 1000
FileB 2000
FileC 3000
Total File Size is 6000

Its not supposed to work in above form. This would:

Code:

awk 'BEGIN {printf ("File Totals")}
{ total = total + $1}
{printf "%20s,%9d\n", $2, $1 }
END {printf "%20s,%9d\n", "Total File size is ", total}' File_Name_Size.txt >> File_Name_Size_Total.txt
