File size not trapped using bourne shell

[myindi]

Hi Gurus,


I have been having trouble finding where I'm wrong.

Problem:

I'm trying list all files exceeding 1.5G everything works fine if I move to bash, but I want to get this to work on bourne shell.

/twork > ls -al
total 12908196
drwxr-xr-x 2 root other 512 May 29 16:20 .
drwxr-xr-x 3 root other 512 May 29 12:43 ..
-rw-r--r-- 1 root other 3302859316 May 29 11:31 a
-rw-r--r-- 1 root other 1992294400 May 29 13:52 b
-rw-r--r-- 1 root other 1310564916 May 29 13:55 c
/work > ls -al|grep -v "^total"|grep -v "d"|awk '{print $5, $9}'|while read si fi
> do
> if [ $si -gt 1500000000 ]
> then
> echo $si size $fi file
> fi
> done
1992294400 size b file
< I expect file &quot;a&quot; to appear in the output ???? >

This is very simple straight forward but it doesn't trap the file &quot;a&quot;. It traps only file &quot;b&quot;.

Workaround:

When I change my shell to bash it works fine but I would like to stick to bourne shell.
/twork > bash
/twork> ls -al|grep -v &quot;^total&quot;|grep -v &quot;d&quot;|awk '{print $5, $9}'|while read si fi
> do
> if [ $si -gt 1500000000 ]
> then
> echo $si size $fi file
> fi
> done
3302859316 size b file
1992294400 size a file
/twork >

I have tried the following but none of the changes trappped file a.
if [ $si -gt 1500000000 ]
if [ &quot;${si} -gt 1500000000 ]


I appreciate any assistance.

Thanks

Your script seems to work OK for me if I replace the &quot;d&quot; in the first line with &quot;^d&quot; to only exclude directories and not any filename containing a d. Is this the problem, or are your files really called a and b? Cheers.

Thanks for your prompt reply.

My problem is when I use bourne shell the script won't detect the files exceeding 2G under my if statement.

When I use bash it works fine.

This is a long script and the rest coded using bourne shell & I'm compelled to stick to bourne shell.

Sorry, I haven't been able to replicate this problem on my Solaris system. What OS are you using, perhaps it's a limitation of ls for largefiles in bourne on it? Anyone else out there got any ideas?

 

[myindi]

I run the script on Solaris 8.

You could do this ?

#!/bin/sh
find . -type f -ls | awk '!$7<1500000000'



Checkout: man find for description of -ls
Note: you may need to play with the values

Good Luck
Laurie.

or use the size options with the find command.
