fileset='APP11.txt APP12.txt SPACEDB11.txt WEB11.txt WEB12.txt'

Hi there,

Give the fileset, if I can use grep to find all the files.

How do I show:

 All Servers:

instead of

 
APP11.txt:
APP12.txt:
SPACEDB11.txt:
WEB11.txt:
WEB12.txt:

If your grep supports the -h option, you could try:

grep -h "something" file*

or if your grep does not know this option, try:

cat file* | grep "something"

You could also use a utility that does not show the file names:

awk '/something/' file*
sed -n '/something/p' file*

Do you want to explicitly show All servers: if a grep ped string exists in all text files mentioned?

Yes to Rudi Question.

Try

awk '
BEGIN   {for (i=2; i<ARGC; i++) T[ARGV]++}
$0 ~ SP {delete T[FILENAME]}
END     {P = 1
         for (t in T) P = 0
         if (P) print "All servers: "}
' SP="Hello" $fileset

Maybe something like this?

for x in a b c; do echo somestring > $x ;done # for testing
                      
[ `grep -l somestring a b c | wc -l` -eq `ls a b c | wc -l` ]  && echo 'All'
All

Try:

awk '
  FNR==1{
    A[f=FILENAME]
  } 
  $0~s{
    F[f]
  } 
  END {
    a=1
    for(f in A)
      if(!(f in F)) {
        a=0
        break
      } 
    if(a) 
      print "All Servers:"
    else
      for(f in F)
        print f ":"
  }
' s=foo file*
