Hi Hans, thanks for your reply. You mean to say that what ever is their between the lines of code <<EOF ...EOF is going to logfile specified. sqlplus -s >> $LOGFILE << EOF -- -- -- EOF you have specified COMMAND ....<< INPUT INPUT so we can use INPUT also ? thanks !!

No, what I meant to say was that the input the sqlplus program expects is put between the <<WHATEVER ... WHATEVER tags. The output of the sqlplus program is redirected to a logfile but unless the sqlplus program can accept it's input through a pipe it's not possible to both redirect input...

I recommend you use a standard shell script like ksh or bash: Code: for filenm in /your/directory/* do awk 'substr($0,60,10) ~ /-/ {n+=1} END {print FILENAME" has "n" lines with dashes.";}' $filenm done

@Mike Quote: In the above script - can u explain me in steps I added comments in the script. It is a good idea in any case. I also changed the script a bit. Code: # DECLARE VARIABLES. var str list, file, content, line, columns60_69 # Get a list of all files in directory "/your/directory". lf -rn "*" "/your/directory" ($ftype=="f") > $list # $list has file names, one...

It is as though the contents were coming from a separate file (and so called a "here"file). The same word signifies the start abnd end of the here file. It could as well have been: COMMAND ....<< ANYWORD ANYWORD instead of COMMAND ....<< INPUT INPUT . The end marker for the here file must start at column 1 (annot be indented). End

Yes, the EOF or INPUT are used to identify where the here-document ends. You can use whichever character sequence you want - as long as the end-marker doesn't occur on a single line within the here-document itself. (It may be part of some other text within the document.) Typically, EOF is used, however.
