Help with an awk output

[chrchcol]

I am using z=`ls -la "$f" | awk '{print $5} to pipe the filenames from one variable into another variable for later output.

However the filenames print left to right, I really need them to print right to left the way they do in the ls -la command

Hi

I do not understand your problem. Could you give us samples of input, wrong output and correct output ?

Well, the output of the ls -la command for size would be the larger sizes would be to the left and on the right the smaller sizes line up. Such as

123456
123
567
33
123456

That would be correct. WHen you use ls -la | awk '{print $5}'

The output looks more like

123456
22
234
235
123457

Hi

So you want right aligned numbers. Not a nice solution :

ls -la | awk '{s[NR]=$5;if(l<length($5))l=length($5)}END{for(i=1;i in s;i++)printf"%"l"s\n",s[i]}'

Hi chrchcol,

If you are using Korn Shell (ksh), you could try:

typeset -R8 z=""
z=`ls -la "$f" | awk '{print $5}
echo "$z"


I hope that helps.

OK now I am totally confused, the code you gave me worked perfect on the command line. It was Right aligned.

<CODE>ls -la | awk '{s[NR]=$5;if(l<length($5))l=length($5)}END{for(i=1;i in s;i++)printf"%"l"s\n",s}'</CODE>

However when I tried to add it into my script and added this

<CODE>
for f in $(<uploads); do x=`ls -la "$f"| awk '{s[NR]=$5;if(l<length($5))l=length($5)}END{for(i=1;i in s;i++)printf"%"l"s\n",s}'`
echo "$x"

Then I run it and it lists the size but its left aligned.

As previously suggested:
for f in $(<uploads); do
[!]typeset -R8[/!] x=$(ls -la "$f" | awk '{print $5}')
echo "x='$x'"
done


Hope This Helps, PH.

Will that also work using Bash?

 

[chrchcol]

I just checked it does not work in bash.

bash claims to be (at least) Posix compliant, so I guess yes perhaps. ;-)

I hope I wasn't being rude, I was just letting you know I could not get the Typeset command to work with those switches. I do see the command for typeset and have been trying to play with it.

I found a command that worked almost completley
<c>z=`ls -la "$f" | awk '{ printf("%-15s\t%10d\n", $9, $5)}'`</c>

This command works perfect. The onlyput I need is $5 though. When I remove $9 it does not work. Is there something I am missing?

And this ?
for f in $(<uploads); do
x=$(ls -la "$f" | awk '{printf "%8d",$5}')
echo "x='$x'"
done
