Hi,

I am trying to use a script to place some text in a file, then read the filenames from a folder, then follow it all with some more text. So that it end up something like this:

starting_text_here file1 file2 file3 finishing_text

But so far I have only managed to get it so that the files are on the same line, ie:

starting_text_here
file1 file2 file3
finishing_text

I have tried using the multi line stuff in sed but I don't really understand how to use it
Thanks

Please clarify your requirements providing a sample input file(s) and sample result file(s) and the code to your script.

Thanks.

OK, sorry.

I have a list of files like this in a folder.

90007-01-11-04Z
90007-01-12-00
90007-01-12-00A
90007-01-13-00
90007-01-13-00A
90007-01-13-00Z
90007-01-14-00
90007-01-14-00A
90007-01-14-00Z
90007-01-15-00A

What I want to do is insert a bit of code at the start of the line, then the file names, followed by a different bit of code.
This is the code that I have so far.

#insert combine script
sed '$a\
\
\
\${combi} all' $EXPATH/combine.tmp > $EXPATH/combine


#search folder for name remove unwanted names, place on same line with awk
ls $EXPATH | grep '^'"$FILE"'.*' | grep -v '_' | grep -v '\.' |
awk '{
printf ("../%s ",$1)
}' >> $EXPATH/combine


sed '$a\
-addclusters -nosyst -top\
' $EXPATH/combine > $EXPATH/combine.tmp

I have so far managed to get all the filenames on the same line, but I can't get the code onto the same line

thanks

Your first grep (grep '^'"$FILE"'.*') combined with the the third grep ( grep -v '\.' ) may not work.

I assume you are wanting to list (ls) all file that begin with "$FILE"? excluding those that have an underscore (_) and dot (.).

Do you want the result in the "$EXPATH/combine" file to be something like this???:

-addclusters -nosyst -top ../file1 ../file2 ../file3

Ok try this:

Code:

EXPATH=/path/to/files
FILE='90007'
echo "`ls -1 $EXPATH | grep "${FILE} | grep -v '_' | grep -v '\.' `"|\
awk 'BEGIN{printf "-addclusters -nosyst -top ";}
{printf " ../%s ",$1;}
END {print ";"}
' >> $EXPATH/combine

Thankyou so much!! You have just removed some of the most cumbersome parts of my code!!

The grep parts appear to work, although I recognise that there may be an issue if I am not careful and there are unwanted filenames without _ or .

Thanks

Glad to help.
