help on unix script

[lamsf]

Hi,
I hv a file with the following contents (eg):

ABCDEF
1234567
GHIJ
23456

What command can I use to modify the file contents to become the following:

ABCDEF 1234567
GHIJ 23456

i.e. the 2nd line will join the 1st line, and so on.

Can someone pls help? Thanks a lot!

What shell do you want to use?

 

[olded]

cat file|xargs -n2

 

[Ygor]

paste -sd ' \n' file

 

[dchoulette]

paste - - < file

The paste man page says:

Example 3: Combine pairs of lines from a file into single lines.
paste -s -d"\t\n" file

Thanks all for helping, really appreciate it.

I hv another question... Can I hv more than one delimiters? For eg. if I hv a file with contents:

12:34;56/78
ab:cd;ef/gh

For the above file, how can set the delimiter to be ":", ";" and "/"?

Thank you all in advance.

Would you want the output to be 12 ab; 34 cd... or 12 34 56 78 ab cd ... ? If you want the former, I'd suggest a perl script to take care of it.
