Three space delimited files

So I have three space delimited files. Each have 90 rows and many columns. I want to merge them by columns. I use paste to merge file 1 and file2 or file 3 and it works. But when I try to merge file 2 and file 3 using paste or merge or cat, I cannot merge them by column, instead they are merged by row. I cannot figure out why, why doesn't it work even though they have the same number of rows? Smilie

I can't tell what you did from this description. Could you show us what you actually typed?

paste works because it's meant to connect lines column by column like that. cat just reads files one by one. I have no 'merge' command at all and don't know what it is.

I used paste 1a.txt 2a.txt > 3.txt

1a.txt contains 90 rows and 2a.txt contains 90 rows as well. But when I use the above function, I get a file with 180 rows. So the paste function does not merge by column, it merges by row.

the paste command does merge column by column. Paste this into your terminal.

Code:
# create file1
cat <<EOF >file1
a
b
c
d
EOF

# create file2
cat <<EOF >file2
g
h
i
j
EOF

# create file3
cat <<EOF >file3
k
l
m
n
EOF

# combine them into text with 4 rows and 3 columns.  It will print to the terminal.
paste file1 file2 file3

Code:
a       g       k
b       h       l
c       i       m
d       j       n

If paste doesn't paste columns there's something wrong with how you're using it. You also mentioned something about cat and merge but gave no further indication of what you did with them.

Didn't you say you had three input files? You're giving it two. If 3.txt was supposed to be an input file, you just overwrite it with garbage.

Code:
paste inputfile1 inputfile2 inputfile3 > outputfile

If it still doesn't work, show us what you actually typed, word for word, letter for letter, keystroke for keystroke. Use screenshots if necessary.

Ok, thanks. It actually worked. I realized that the files were indeed merged column by column.

However there is another issue. I want each row to correspond to a single line, now it splits rows into two lines. How do I format the file so that each row corresponds to a single line? Thanks a lot and sorry for the confusion! Smilie

I don't suppose any of those input files were edited with notepad? the extra carriage returns Windows fills everything with will make them do weird things when used with UNIX commands.

They might have been. The files were given to me by someone. Is there a way to fix it?
