Hi Nag!
Do a script that you can call appendfile.sh

then:
cat filex >> file1
cat filex >> file2
cat filex >> file3

and so on....

chmod 755 appendfile .sh
then execute the file.
./appendfile.sh

You can avoid repitition by using a loop, eg

for f in f1 f2 f3 f4 f5 f6 f7 f8 f9 f10
do
cat x >> $f
done

Where f1-f10 are your file names.
Or, if your 10 files patch a pattern, (eg *.txt), use

for f in *.txt
do
cat x >> $f
done

Hi,

the shell does no expansion of things like * after a redirection >. Graham has the simplest solution.

greetings,

Give this a try

#!/usr/bin/ksh
filedir=/dir_where_files_are

files=$(ls $filedir | grep -v fileX)

cat $filedir/fileX >> $files

ignore the post above... this one is better

#!/usr/bin/ksh
filedir=/dir_where_files_are

files=$(ls $filedir | grep -v fileX)
for i in $files
do
cat $filedir/fileX >> $i

Ok... it's either early or I'm retarded :) I forgot to put a "done" as the last line of the script above. It should be

Nag,

The simplest way to append a string of test to the end of an existing file is to use the echo command.

echo "text to append" >> file

Using the cat command requires that you create a new file with your text to append.

If the directory contains just the 10 files that you want to append to, then you can do the following:

for i in *
do
echo "text to append" >> $i
done

if the problem is solved, could you spare some points from the endless supply of points, HP has, for those, who could help you? ;-)

Negendra, i hope that i have understood....
Considering that the files are only 10, i think to commands manually.
With the command "vi" (or "ed" or "ex") you extract the part of text from the fileX and saves it in fileY.
# vi fileX

Then with the command "cat" you append fileY to all the files.
# cat filey > > file1
# cat filey > > file2
# cat filey > > file3
(...repeat for all files)

You can avoid repetition by using a script with cicle "for".
Like explanation by others answers previous (of others user).
