UNIX for Dummies Questions & Answers

Hi,

I would like to know , how to concatenate two command in one line and get the display in one screen

for eg

command 1 : ls -l /data/logs
command 2 : ls -l /data/errors

output shd be

/data/logs /data/errors
xx-xx-xx-xx abc.log xx-xx-xx-xx abc.err
xx-xx-xx-xx abc1.log xx-xx-xx-xx abc1.err
xx-xx-xx-xx abc2.log xx-xx-xx-xx abc2.err

is this kind of output is possible , pls help

How about this ?

Code:

#! /bin/sh

for logs in `ls /data/logs`
do
LOGS="$logs"
  for err in `ls /data/errors`
  do
  ERR="$err"
  echo "$LOGS  $ERR"
  break
  done
done

Vino

vino

in the script that u had provided

all the files under the first for loop (outer for loop) would be listed

and since there is a break statement in the second for loop
for all the files from the outer for loop only the first file would be printed from the second loop.

To put in more specific terms
ls /data/logs
1.txt
2.txt

ls /data/errors
3.txt
4.txt

output would be:
1.txt 3.txt
2.txt 3.txt

the file 4.txt will not be listed

but the required output is of the form
xx-xx-xx-xx abc.log xx-xx-xx-xx abc.err
xx-xx-xx-xx abc1.log xx-xx-xx-xx abc1.err
xx-xx-xx-xx abc2.log xx-xx-xx-xx abc2.err

plz let me know if i had misinterpreted anywhere .

***********************
you can try this... (this is not an efficient way)

ls -l | /data/logs | grep -v total | awk '{print $1, $9}' > t
ls -l | /data/errors | grep -v total | awk '{print $1, $9}' > t1

paste -d"\t" t t1

would give the required output

i am getting the display like

total total
3624 total
-rw-r--r-- total
1 total
roam total
oradba total
3575834 total
Jul total
1 total
12:04 total
access.log total
-rw-r--r-- total
1 total
roam total
oradba total
7 total
Jul total
1 total
12:00 total
access_pointer.txt total
-rw-r--r-- total
1 total
roam total
oradba total
88051 total
Jul total
1 total
12:04 total
kannel.log total

your output seems to have

string total

but i had used grep -v total no way u can get total

ls -l | /data/logs | grep -v total | awk '{print $1, $9}' > t
ls -l | /data/errors | grep -v total | awk '{print $1, $9}' > t1

paste -d"\t" t t1


can u please the change the command to following

ls -l /data/logs | grep -v total | awk '{print $1, $9}' > t
ls -l /data/errors | grep -v total | awk '{print $1, $9}' > t1

paste -d"\t" t t1

and let me know how do u proceed.

actually that output is for the earlier script which u gave.. pls ignore

i have ran the latest script and got the output like this

-rw-r--r-- afiedt.buf drwxr-xr-x analysis
-rw-r--r-- analyzer.log drwxr-xr-x gdbm
-rw------- cancel.gdbm drwx------ lost+found
-rw-r--r-- change.log -rw-r--r-- message.log
-rw-r--r-- counters.log.bz2 -rw-r--r-- roamer.log
-rw------- dbm_messenger.dbm
-rw-r--r-- dp5.log

yes, the output is fine, but the thing is it is not aligned , is there any way i can get like

-rw-r--r-- afiedt.buf <space><sapce> drwxr-xr-x analysis
-rw-r--r-- analyzer.log<space><sapce> drwxr-xr-x gdbm
-rw------- cancel.gdbm<space><sapce>drwx------ lost+found
-rw-r--r-- change.log<space><sapce>-rw-r--r-- message.log
-rw-r--r-- counters.log.bz2<space><sapce>-rw-r--r-- roamer.log
-rw------- dbm_messenger.dbm
-rw-r--r-- dp5.log

i believe the <space> that u had mentioned are <tabs> if i am right

and the output u obtained is what u required right ???

so what is the required format for ur output, send us that also.
