hi there,

What i'm trying to do is have this

nano file1

line1
line2
line3
line6

nano file2

line2
line3
line4
line5

compare the two files (some command file2 & file1)

and then output a third file,

nano file3

line1
line2
line3
line4
line5
line6

with all the contents of the first two files without making a copy of any of the information.

I want to synchronize content of the two files without making duplicate entries

cat file1 file2 | sort -u file3

is a quick solution.


Cheers,
Tink

Tinkster's entry is missing a redirect sign (perhaps dropped from the formatting).

I believe Tinkster meant to put:
This assumes that the entries are to be sorted alphabetically.

I did indeed - thanks for the corrective feed-back :}

A more complex solution that doesn't sort the results be easily accomplished
using awk (it's non-deterministic, though):
[code]
awk '{entries[$0]=$0} END{ for (i in entries) print entries[i]}' file1 file2 > file3
[code]


Cheers,
Tink

I would like to make a file3, wich will have all lines from file 1 but only if that lines are not in file 2

Is something like that possibile to do from the bash or i need some programing language ?

Please help me !
thanks !

I have done this by now :
-----------------------------------------------------------
#!/bin/bash
unixfiles=` cat /program/unixfiles.txt`
files=` cat /program/files.txt`

for i in $unixfiles; do
echo $i
for fa in $files; do
echo "UN, $fa"
if [ "$i" = "$fa" ]; then
echo "same" >> /program/state.txt
else
# cat "$fa" >> /program/samefiles.txt
echo "not same" 1>> /program/state.txt
fi
done
done
exit
------------------------------------------------------------
I think that it is working but i don't know why i cant use
cat "$fa" >> /program/samefiles.txt
if i use that comand then i get some error message !
Does somebody know why ???
