UNIX for Dummies Questions & Answers

Hi,

How do I format the following?
I have a for loop that retrieves me the path and file name of a file. In column fashion I would like to add the time and another variable containing the file's size. This will result in all the time being under each other and all the file size's being under each other. This is for logging purposes, so this will all go to file. The headings are not important.


File path variable time size

ex.
/path1/...... 10:00:00 30
/path2/.. 00:00:12 7000009
/path3/............. 12:12:31 2

Please assist.

echo " Name Time Size "

Inside the for loop try this :-

ls -lrt $file | awk '{print $9; print $8; print $5}' | tr '\n\ ' '
echo " "

where file is the file retrieved from the loop

Why the tr after the awk and also the multi - print's?

Code:

ls -lrt $file | awk '{print $9 "\t" $8 "\t" $5}'

Thats a tab-delimited output.

Not tested tho'.

Sorry guys, I was maybe not to clear of what is known and how it must be formated. Most of the data is retrieve by the for loop into variables.

This is the columns.

Code:

<tab>                      <tab>                            <tab>            <tab>
"File path variable"     "time for date command"    "size old var"   "size new var"
/path1/.....               23:00:00                         30                 2
/path2/.....               04:01:02                         99999999        4         
/path3/.....               01:00:55                         40                 15

Thanks a lot for you prompt response though.

Show us a sample of the input and the the output you require.
Probably that could help.

This is the format of my current log file after the script has run.

/edi/iTracTEST/sessions/otherreceive/nohup.out @ 08:19:46 from 63 - 63
/edi/iTracTEST/sessions/payroll/nohup.out @ 08:19:46 from 52395 - 63
/edi/iTracTEST/sessions/payrollmsg/nohup.out @ 08:19:46 from 56931 - 63

As from the first record/line.
The path and file name is already in a variable from a the for loop in the script.
The "@" is echoed.
The time is coming from the date command.
The "from" is echoed.
The first 63 is the initial file size in bytes as from a variable in the for loop.
The "-" is echoed.
The second 63 is the current/new file size as from a variable in the for loop.

I would like the log file to look like this. !!!Notice I have swapped the sizes!!!

/edi/iTracTEST/sessions/otherreceive/nohup.out 08:19:46 63 63
/edi/iTracTEST/sessions/payroll/nohup.out 08:19:46 63 52395
/edi/iTracTEST/sessions/payrollmsg/nohup.out 08:19:46 63 56931

This just make the log file more readable.
Here is some of the code, thus far.

sess_path=/edi/iTracTEST/sessions/
ls -pl /edi/iTracTEST/sessions/ | awk '$1 ~ /^d/ $9 ~ /\/$/' | awk '{print $9}' > `pwd`/temp/`date +"%C%y%m%d"`.tmp
for nohup_loc in $(cat `pwd`/temp/`date +"%C%y%m%d"`.tmp)
do
nohup_loc2=$sess_path$nohup_loc"nohup.out"
if test -s $nohup_loc2
then
cur_fsize=`ls -l $nohup_loc2 | awk '{print $5}'`
echo !!! Reset nohup.out file at `date` !!! > $nohup_loc2
new_fsize=`ls -l $nohup_loc2 | awk '{print $5}'`
echo $nohup_loc2 @ `date +%H:%M:%S` from $cur_fsize - $new_fsize >> `pwd`/log/`date +"%C%y%m%d"`_nohup_reset.log
fi
done
