Picking matching strings
I have a list of file names. However in some instances I might have a "-" at the beginning of the filename or an "=".

For example I might have something like this

Code:
set Lst = "file1 file2 file3 -file4 file5="

I want to pick up the ones having "-" at the beginning or "=" and store them in AierrLst.

Have coded the thing below. Would be good to have suggestions.


Code:
set ierr1 = 0
set AierrLst = ""
foreach f ($Lst)
  set cerr = `echo $f | awk '/^-|=/'`  # Matches "-" or "="
  if ("$cerr" != "") then
    set AierrLst = "$AierrLst $f"
    if ($ierr1 == 0) echo ""
    echo "ERROR. $f  Argument option does not exist."
    MATH ierr1 = $ierr1 + 1
  endif
end

Does this give you some ideas?
Code:
$ echo "file1 file2 file3 -file4 file5="
file1 file2 file3 -file4 file5=

$ echo "file1 file2 file3 -file4 file5=" | tr " " "\n"
file1
file2
file3
-file4
file5=

$ echo "file1 file2 file3 -file4 file5=" | tr " " "\n" | grep [\-\=]
-file4
file5=

$ echo "file1 file2 file3 -file4 file5=" | tr " " "\n" | grep [\-\=] | tr "\n" " "
-file4 file5=

Code:
echo "file1 file2 file3 -file4 file5=" | tr " " "\n" | grep [\-\=]

returns "grep: No match."

Tried this to no avail

Code:
echo "file1 file2 file3 -file4 file5= file-6" | tr " " "\n" | awk '/^-/ && /=/'

Hi.

None of the names begin (^) with - and (&&) end ($) with = at the same time. Perhaps that && should be || (or)?:
Code:
$ echo "file1 file2 file3 -file4 file5= file-6" |  awk '/^-/ || /=$/' RS=" "
-file4
file5=

Code:
echo 'file1 file2 file3 -file4 file5= file-6"'| tr ' ' '\n' | nawk '/^[-]/ || /[=]$/' | tr '\n' ' '

Oh yes, I made that bit up Smilie

(assuming you used a ^ with - that a $ (end of line) would be useful for =)
