Merging lines into one

Foxgard · #1 (**permalink**) 06-18-2005

Hello. I would be very pleased if sb. help me to solve my problem. I've got a file with many non blank lines and I want to merge all lines into one not destroy the informations on them. I've tryed it with split and paste, tr, sed , but everything I've done has been wrong. I know about crazy solution but I don't want to do it this way. Don't forget the simplier way is the better.

tr -d '\n' < file

You don't understand me.

I've filled up my problem with red-coloured text to U understand me. Your solution only deletes all the newlines "\n". And that I didn't want to do with the file.
e.g.
from
A
B
C
into
ABC

How is that different from deleting the newline characters?

I see how you want it to work, but it doesn't work. When I send the command to bash, it deletes all the lines from input. I've had some problems with intepretation of the commands even if the command was standard before. I use the xandros 3.01,GNU bash version 2.05b.0(1)-release (i386-pc-linux-gnu). May the problem be in my OS?

Code:

$ cat > test.txt
a
b
c
d
e
f
g
h
i
j
k
l
m
n
o
p
q
r
s
t
u
v
w
x
y
z

Code:

#!/bin/bash
#
# append.sh
#
while read line ; do
    printf ${line}
done < $1

Code:

$ ./append.sh test.txt
abcdefghijklmnopqrstuvwxyz
$ tr -d '\n' < test.txt
abcdefghijklmnopqrstuvwxyz
$ awk '{prinf $0}' file.txt
abcdefghijklmnopqrstuvwxyz

Code:

bash:cat /tmp/test$$ -prints this
#define hcv 54
 #define f 8
  #define s 354
 jae
 feh
  h
  f*h
  adssfh

#the whole code isn't necessary to read only the output of cat /tmp/test2$$ and output of file$$

Code:

bash:sed "/#define.*/w /tmp/test$$" test ; sed '{s_[/t ]*#define[\t ]\+\(\<.\+\>\)[\t ]\+\(\<.\+\>\)_\{s/\1/\2/\};_}' /tmp/test$$ > /tmp/test2$$ ; cat /tmp/test2$$ | tr -d '\n' > file$$; cat file$$ -prints nothing
bash:cat /tmp/test2$$ - prints that should print
{s/hcv/54/};
{s/f/8/};
{s/s/354/};

This is the whole problem I've got and I don't understand why It doesn't work
*mistake by rewriting the code to here, because I read in my code the name of the file from $prom, now it is right
