UNIX for Dummies Questions & Answers

i have:

file1 contains: 123abc
file2 contains: 123 abc

i used:

paste file1 file2 > file3, and the output looks like this:

123abc 123 abc

i used:

cat file3 | awk '{print $1, $2}' > file4, result: 123abc 123

my intention is to get file looks like this:

123abc123 abc

when i use paste, it merges columns, but it put space. i want pasted each file, but i don't want any space.

Since I don't know awk much, I suggest using sed

cat file3 | sed 's/ //g'

how about this.

Code:

paste -d \0 file1 file2

beware of UUOC

one more,

Code:

awk 'BEGIN{ORS=" "}{ print }END{ printf"\n" }' file1 file2

Point noted.

paste and awk worked perfectly.

sed worked, but i did not want to delete a certain space.

again, you guys are GURU, and thank you very much.
