cat without new line


I have a problem, I want to cat something but I don't want that after every parameter I get a new line, particularly I need that the output of :
Code:
cat /proc/sys/dev/sensors/asb100-i2c-0-2d/in0 /proc/sys/dev/sensors/asb100-i2c-0-2d/in1 /proc/sys/dev/sensors/asb100-i2c-0-2d/in2 /proc/sys/dev/sensors/asb100-i2c-0-2d/in3 /proc/sys/dev/sensors/asb100-i2c-0-2d/in4 /proc/sys/dev/sensors/asb100-i2c-0-2d/in5 /proc/sys/dev/sensors/asb100-i2c-0-2d/in6
will not be :
Code:
1.39 2.08 1.81
1.39 2.08 1.81
2.96 3.63 3.28
2.67 3.28 3.02
2.51 3.79 3.28
0.00 0.00 3.28
0.00 0.00 3.28
but instead :
Code:
1.39 2.08 1.81 1.39 2.08 1.81 2.96 3.63 3.28 2.67 3.28 3.02 2.51 3.79 3.28 0.00 0.00 3.28 0.00 0.00 3.28
anyone would know how to accomplish this ?

that would be
Code:
cat <whatever> | tr -d '<string to delete>'

note that
Code:
cat <whatever> | tr '\n' ' '
will replace newlines with space character.

thanks dude !, yet it's still not exactly as I want it to be though ......

it seems that -d takes whatever in ' ' as independent chars, I need it to be a real string.

to delete words, you need sed, not tr. they are different tools, and do their own function very well. see the sed manpage for details, but essentially... "cat blah | grep s/la/ooo/g" will give "boooh"

though grep gave me an error, I quickly (after reading the manual for sed) figured that you actually mean sed.

thanks dudes, you've been VERY helpful !

also I found a strange thing ...........if you give cat more than 4 files and then pipe them through
Code:
| tr '\n' ' '
the
Code:
tr '\n' ' '
part doesn't work, maybe it has a limit on the number of operations
