Data Help cannot concatenate Ksh variables ?
Cannot combine these two strings into one line, either as a 3rd variable or echo or printing ? Frustrating.

Code:
for i in `cat /scripts/pathList.dat`
do
    OldRepo= grep Oldhostname ${i}/.svn/entries | tail -1
    NewRepo= grep Oldhostname ${i}/.svn/entries | tail -1 | sed '/Oldhostname/ s/Oldhostname/Newhostname/g' | sed 's/\/oldpath1//g' | sed 's/\/oldpath2//g'
    echo "cd $i"
    echo "svn relocate $OldRepo $NewRepo" 
done

this always returns:
Code:
cd /path   ( this is ok )
svn relocate $OldRepo  
$NewRepo

Code:
I want "svn relocate $OldRepo $NewRepo "    all on the same line

I have tried RepLoc="$OldRepo $NewRepo"
echo $RepLoc with the same result each on a separate line.

and numerous others using echo -e with \c but nothing I do will concatenate $OldRepo $NewRepo

Please advise
Smilie

Possible that your data files contain MS-DOS control characters.

Can you post a sample of a representative file using this "sed" statement which is designed to make control characters visible.
Code:
sed -n l .svn/entries

Also, I assume that the missing backticks on lines 3 and 4 of the script in post #1 are because this post came via a Microsoft editor?

The script was written on a RedHat linux server using vi
The script was ran on the same Linux server using directories copied from a Windows server to a NAS mounted to the Linux server.

This post was created from an iMac (lion 10.7.x) using TexEditor application ( cut and paste from linux vi saved files.

in each path below there is a .svn/entries file the hostname is extracted from this file

Try updating this line.
Code:
OldRepo= grep Oldhostname ${i}/.svn/entries | tail -1

to
Code:
OldRepo= grep Oldhostname ${i}/.svn/entries | tail -1 | tr -d '\n'

this was an improvement. Both strings are now echo'ed together. Thanks

Now I just need "svn relocate" in the front of them and a space between OldRep and NewRep.

We'd still like to see a sample of the ".svn/entries" file displayed with the "sed" I mentioned earlier. This would tell us what the line terminators are in this file and whether it is a recognisable text file format.

Further to bsrepellant, I suspect that we'll need to remove carriage-return characters (\r) not linefeed characters (\n).


With a bit of lateral thought we can use the same sed display to show what the script is actually outputting (rather than what it looks like on the screen):
Code:
./scriptname   |  sed -n l

almost got it just changed to this (space not working yet):
Code:
echo -e "svn relocate\c" $OldRepo" " $NewRepo
