[SOLVED] loop not working in bash

michaelk · 02-09-2016, 09:00 AM

Does the file with the actual name file.8 actually exist?

chewinghum · 02-09-2016, 09:08 AM

how is this possible to ignore a condition... if it's written wrong it should give an error or something...

chewinghum · 02-09-2016, 09:11 AM

Yes, the file exists.

linux is case sensitive. The name must match exactly for the statement to be true. I see nothing wrong with grail's code.

should i post another question? cause now the loop is working, the problem is the ignored condition.

chewinghum · 02-09-2016, 09:24 AM

this works:

Code:

[ "$1" == "z" ] && [ ! -z "$2" ]

this works too:

Code:

[[ "$1" == "z" && -n "$2" ]]

the loop works, but the last condition inside the loop is ignored.

Nope, post your actual code. Just to make sure post the file name i.e the output of
ls -l file*

You mean this below ? How can this help you ?

[root@localhost scr]# ls -l scr

You indicated that file.8 exists but since linux is case sensitive I wanted you to make sure by posting the output of the ls command i.e.

ls -l file*

my god this is great. file did not exist. i really ment file-$no, not file.$no.
thanks a lot and sorry for the wasted time.

off the top of my head -- check your quotes --
as soon as it finds a true match to a file whatever 'no' is then it will break, i don't know what the rest of your code looks like. but this is just an idea.

try your code but change this to

Code:

""file"."$no""

Code:

end=100

if [ "$1" == "z" ] && [ ! -z "$2" ] ; then

    while [[ "$no" < "$end" ]] ; do 
       echo "$no"
      if [[ -f ""file"."$no"" ]] ; then
          break
else
  (( no++ ))

done
	 
fi

never mind I just read that last post .. lol
mark solved thanks
