I have the following file aa1 uno dos tres cuatro and I want to have it as uno dos tres cuatro I make the following thing: sed '1,$j' aa1 and he responds me sed: command garbled: 1,$j as I can make it?

sed -e :a -e '$!N;s/\n/ /;ta' aa1 uno dos tres cuatro echo `cat aa1` uno dos tres cuatro echo $(cat aa1) uno dos tres cuatro cat aa1 | xargs uno dos tres cuatro (Credit nails for the last solution) In the absense of a specified command, xargs defaults to the echo command.

Another way is to use the tr command to replace new-lines with spaces: tr '\n' ' ' < aa1

And probably the best way. Thanks nails, I keep forgetting about tr.

thank you Jim Boothe and nails for your answers to tell you that they have given me problems the following ones: sed -e :a -e '$!N;s/\n/ /;ta' aa1 N;s /: Event not found echo $(cat aa1) Variable syntax "La experiencia es algo maravilloso. Nos permite reconocer un error cada vez que lo volvemos a cometer.", Franklin P. Jones

Well, that echo is korn/bash shell syntax (sorry, should have mentioned that). But I would have expected the sed command to work. The sed command that you reposted is correct. What shell are you using? echo $SHELL If you have korn shell available, invoke a korn shell by typing ksh, then try both of those commands and report the results. Thanks.

I have cshell I will prove with korn shell "La experiencia es algo maravilloso. Nos permite reconocer un error cada vez que lo volvemos a cometer.", Franklin P. Jones
