Problem with sed
Hi,

I facing some problem while doing sed .
I have simple script.
Code:
#!/bin/sh
set -x
set -v
Test1=""

sed        -e s/dbccons_sparc/dbccons_linux/ \
              -e s/\${SOLARISMACH}/${Test1}/ \
              -e  s+'\"[ \t]*<<'+' \t<<'+ \
              -e s/\"\${DBCCONS}/\${DBCCONS}/ \
              -e  s+'\"[ \t]*\\'+' \t\\'+ \
              -e  s/rsh/${Test1}/ test.res > test.output

its executing fine but when I edit that script without any change and then saving it and compiling its throwing error.

Code:
+ set -v
Test1=""
+ Test1=

sed        -e s/dbccons_sparc/dbccons_linux/ \
              -e s/\${SOLARISMACH}/${Test1}/ \
              -e  s+'\"[ \t]*<<'+' \t<<'+ \
              -e s/\"\${DBCCONS}/\${DBCCONS}/ \
              -e  s+'\"[ \t]*\\'+' \t\\'+ \
+ sed -e s/dbccons_sparc/dbccons_linux/ -e 's/${SOLARISMACH}//' -e 's+\"[ \t]*<<+ \t<<+' -e 's/"${DBCCONS}/${DBCCONS}/' -e 's+\"[ \t]*\\+ \t\\+' ' '
sed: can't read  : No such file or directory
              -e  s/rsh/${Test1}/ test.res > test.output
+ -e s/rsh// test.res
./sample.sh: line 11: -e: command not found

Same problem :
Code:
#!/bin/sh
sed        -e s/dbccons_sparc/dbccons_linux/ \
              -e  s/rsh/no/ test1.res > test1.output

test1.res contain :
rsh dbccons_sparc

but when I am just editing without any changes its throwing error.
Code:
+ set -v

sed        -e s/dbccons_sparc/dbccons_linux/ \
+ sed -e s/dbccons_sparc/dbccons_linux/ ' '
sed: can't read  : No such file or directory
              -e  s/rsh/no/ test1.res > test1.output
+ -e s/rsh/no/ test1.res
./sample1.sh: line 6: -e: command not found

Don't use -e and quote your sed commands. Sed is a independent from a shell and its language doesn't have anything common with shell language:
Code:
sed  's/dbccons_sparc/dbccons_linux/
s/rsh/no/' test1.res > test1.output

If I need to do some opration like : s+'\"[ \t]*\\'+' \t\\'+
how to keep this in this code.
Code:
sed  's/dbccons_sparc/dbccons_linux/
s/rsh/no/' test1.res > test1.output
