Hi, Thank you very much for the good advices. Now, to a question more related to linux. I wrote this small script to get a more pleasing output from bidiv: #!/bin/sh case $# in 0)echo "Use: $0 file_name width additional_options";; 1)echo "Use: $0 file_name width additional_options";; *) Z1=$1; Z2=$2; shift 2; Z3=`expr $Z2 + 10`; Z4=`expr $Z3; + 9`; cat $Z1 | sed 'G' | fmt -w $Z2 | bidiv -j -w $Z3 | sed -e :a -e "s/^.\{1,$Z4\}$/ &/;ta" | sed '/^$/d' $*;; esacIt does what it is supposed to do, but issues every time the following error message: /home/avraham/scripts/newbidiv: line 1: +: command not found I see no + over there. I entered this line in the script in Vim through :r ! head -1 some-other-script (because, otherwise, from time to time I enter !# instead of #!) and /bin/sh is indeed a link to bash. I do not receive this error message with any other of my scripts. Any ideas ?
Could "Z4=`expr $Z3; + 9`" be the problem? It basically says: 1. Evaluate $Z3 2. Wait for expr to finish 3. execute "+" with 9 as $1 parameter.
