Homework and Emergencies Homework & Coursework Questions Asst: Shell Script to sed
# 15  
The conversion from l* to l\* would happen in the code that you commented out.
Where
A="`cat target`" is problematic, should be a simple read A < target
# 16  
Without the quotes I get the same error message. Looking through the -x log it shows lots of blank spaces which my sed handles fine. I assume it is that asterik not converting to plain text with my sed command that is messing it up. I've been messing around some more with the quotations because I figure that is where I messed up. I read that * has special characteristics while in double quotes so maybe that is it?

Code:
37...
+ p1=l*
+ shift
+ p2=L
+ shift
+ echo l*
+ echo L
+ echo Process _cat.dog.dat using l* and L...
+ + sedecho l*
 -e s/\([*.[^$]\)/\\\1/g
+ read l*
/home/sofestafont/UnixCourse/scriptAsst/sub3: 15: read: l*: bad variable name
+ rm temp
+ echo p1 = l*
+ sed s/l*/L/g _cat.dog.dat
+ mv temp.out _cat.dog.dat
+ echo l*
+ echo L
+ echo Process /home/sofestafont/UnixCourse/scriptAsst/../_hippo.cpp using l* and L...
+ + sed -eecho l*
 s/\([*.[^$]\)/\\\1/g
+ read l*
/home/sofestafont/UnixCourse/scriptAsst/sub3: 15: read: l*: bad variable name
+ rm temp
+ echo p1 = l*
+ sed s/l*/L/g /home/sofestafont/UnixCourse/scriptAsst/../_hippo.cpp
+ mv temp.out /home/sofestafont/UnixCourse/scriptAsst/../_hippo.cpp

sub3 produced incorrect output on test 37: /home/sofestafont/UnixCourse/scriptAsst/sub3 'l*' 'L' '_cat.dog.dat' '/home/sofestafont/UnixCourse/scriptAsst/../_hippo.cpp'

I tried changing the quotations around the parameters in the last sed value all to no avail. I don't understand, why it says l* is getting passed but the output is wrong. I've incorporated the read command.
Code:
#!/bin/sh
set -x
p1=$1
shift
p2=$1
shift

for FILE in "$@"
do
        echo $p1
        echo $p2
        echo "Process $FILE using $p1 and $p2..."

        echo "$p1" | sed -e 's/\([*.[^$]\)/\\\1/g' > temp
        read $p1 < temp
        rm temp
        echo "p1 =" $p1

        sed "s/$p1/$p2/g" "$FILE" > temp.out
        mv temp.out "$FILE"
done

~/UnixCourse/scriptAsst/sub3 *l L myFile1.txt myFile2.txt myFile3.txt
Is the input that is messing me up.
# 17  
Code:
read p1 < temp

no $
It's an assignent to p1 not a reference of $p1
