remove spaces btw

tjmannonline · #1 (**permalink**) 05-15-2008

filename contains:

123 4
1234 5
12345 689

i want result:
1234
12345
12345679

cat filename | awk '{print $1, $2, $3}' will get my result, but too many $$s.

sed -e 's/[ ]//g' filename will take care one space, [ ] will take 2 spaces.

is it a short way to do this ?

Code:

awk '{gsub(" ","")}1' file

The gsub function substitutes all spaces with nothing and awk evaluates the 1 as true and prints the entire line.

Code:

tr -d ' ' <file

tr replaces characters with other characters, or, with the -d option, with nothing.

I think this is the easiest answer and also good implementation of RE.
