No way, this will remove the leading space for INFO row, but it will report all the rest from info.tmp file... :-(

@pamu, this is just a test and I report only a sinple text! Smilie

Ok, then try this:
Code:
# INFO="$(sed -n '/INFO/ {s/^ *//p}' info.tmp)"
# echo "FIELD1; FIELD2; $INFO; FIELD4"
FIELD1; FIELD2; INFO : ABCDEFG; FIELD4

Ok this extract only the INFO field, but why I have this output?!?!?!?! Smilie

Code:
INFO="$(sed -n '/INFO/ {s/^ *//p}' info.tmp)"
echo $INFO
echo "FIELD1 ; FIELD2 ; $INFO ; FIELD4"

Result:

Code:
# ./test.sh 
INFO : ABCDEFG
  ; FIELD4FIELD2 ; LA_INFO : ABCDRFG

Try with this...

Code:
INFO=$(grep -i INFO /info.tmp | sed 's/^ *//')

OK, THAT'S CRAZY!!!

This works, but I believe work also the other solution:
Code:
INFO=$(grep -i INFO /info.tmp | sed 's/^ *//')
echo "AAA ; BBB ; CCC ; $INFO"

Output:
Code:
# ./test.sh 
AAA ; BBB ; CCC ; INFO : ABCDEFG

This doesn't work, and I don't understand why:
Code:
INFO=$(grep -i INFO /info.tmp | sed 's/^ *//')
echo "AAA ; BBB ; CCC ; $INFO DDD"

Output:
Code:
 DDD; BBB ; CCC ; INFO : ABCDEFG

You see? I only add a simple text after $INFO variable!!!!

I am not getting what's problem with your bash..Smilie

here i am getting perfect...

Code:
$ cat file3.sh
INFO="INFO : ABCDEFG"
echo "AAA ; BBB ; CCC ; $INFO DDD"

$ ./file3.sh
AAA ; BBB ; CCC ; INFO : ABCDEFG DDD

and in your previous post also... If you are getting $INFO right it should work for all the scenarios..Smilie
