Posted a Question Yesterday

Was wondering if it was too stupid and got deleted? Because it's gone now from the board.

I was asking about For Loops ----?

#!/usr/bin/bash

bank=`cat /export/home/usr/banklist.txt`
cdir=`cat /export/home/usr/mountlist.txt`
for d in $cdir
do
ls -l /apps/data/custdata/$d/$i/incoming/
ls -l /apps/data/custdata/$d/$i/outgoing/

for d in $bank
do

ls -l /apps/data/custdata/$d/$i/incoming/
ls -l /apps/data/custdata/$d/$i/outgoing/
done;
done;

The question was asking how to fill in the variables from two different lists of files and when they match peform an action ls -ltr for example?

If this gets deleted it must mean I need to go to the Unix for dummies thread?

Sorry. We had a technical problem yesterday and lost the database. We restored a backup, but we lost a couple of hours of posts.

I don't understand your question, but you show two "for" loops, one nested inside the other. No problem there. But both are using the same variable d. The inner loop needs its own variable.

Ok well not sure I have one list say

lisa a

1
2
3
4

list b

d
e
f
g

So I need something like if $a and $b exist at the same time, then do

ls -l /apps/data/custdata/$a/$b/incoming/
ls -l /apps/data/custdata/$a/$b/outgoing/

The problem being soemtimes there will be an /apps/data/custdata/1/d/incoming/ directory but there will be also times when an /apps/data/custdata/3/f/incoming/ won't exist --- I want to do an ls on the two combos from the two different list files that match?

Try something like:

Code:

for a in 1 2 3 4 ; do
   for b in d e f g ; do
       if [[ -d /apps/data/custdata/$a/$b/incoming/ ]] ; then
          ls -l /apps/data/custdata/$a/$b/incoming/
       fi
       if [[ -d /apps/data/custdata/$a/$b/outgoing/ ]] ; then
          ls -l /apps/data/custdata/$a/$b/outgoing/
       fi
   done
done

That -d is just testing to see if a directory exists with that path.

I got zero out put when I ran the script so I did set -xv

and I got data like this

+ [[ -d /apps/data/custdata/tmp2/noma/outgoing/ ]]
+ [[ -d /apps/data/custdata/tmp2/lima/incoming/ ]]
+ [[ -d /apps/data/custdata/tmp2/urma/outgoing/ ]]
+ [[ -d /apps/data/custdata/tmp2/filoma/incoming/ ]]
+ [[ -d /apps/data/custdata/tmp2/triloma/outgoing/ ]]
+ [[ -d /apps/data/custdata/tmp2/cbass/incoming/ ]]
+ [[ -d /apps/data/custdata/tmp2/estate/outgoing/ ]]
+ [[ -d /apps/data/custdata/tmp2/fondu/incoming/ ]]
+ [[ -d /apps/data/custdata/tmp2/kingson/outgoing/ ]]
+ [[ -d /apps/data/custdata/tmp2/lupra/incoming/ ]]
+ [[ -d /apps/data/custdata/tmp2/jag/outgoing/ ]]
+ [[ -d /apps/data/custdata/tmp2/tyson/incoming

So it looks like it passed the if statement but doesn't get a + for the ls ?

Do those directories, as listed, exist?
