Problem in using sed commnad in bash program.

ASRaj · 03-17-2008, 03:11 AM

hi All,

here is my problem
I try to use "sed" command as followig but I got error!

path=(`pwd`)
.
.
sed 's/home\/aruna\/WORK\/GUI_test\/testharness/($path)/g' run.tcl >> run1.tcl

I cann't figure out what is the problem with this. When I print path on screen it was having a correct value.

I think the problem is that path is having "/" characters inside it.

can you please give me a solution for this?

Thanks,
Aruna.

cat run.tcl | sed s/'home\/aruna\/WORK\/GUI_test\/testharness'/($path)/ >> run1.tcl

Code:

path=(`pwd`)

you're trying to save the output as an array..
that should be

Code:

path="`pwd`"

then use @ as a replacement for forwardslash so that you don't have to quote them anymore

Code:

sed s@home/aruna/WORK/GUI_test/testharness@"${path}"@g run.tcl >> run1.tcl

hi,

It's not working and following is the error message

/home/aruna/WORK/GUI_test/testharness

./rtest: line 46: syntax error near unexpected token `('
./rtest: line 46: ` cat run.tcl | sed

s/'home\/aruna\/WORK\/GUI_test\/testharness'/($path)/ >> run1.tcl'

Thanks,
Aruna.

Hi,
Below is a code that should work fine. The problem is with the "pwd" command, because it returns the value something like "/home/arun". Which contains "/" slashes and you were passing it as it to sed without using the "\" slashes. So, you first need to convert "/" slashes to "\/":

path=$(pwd)
path=$(echo $path | sed 's/\//\\\//g')
.
.
.
sed 's/home\/aruna\/WORK\/GUI_test\/testharness/$path/g' run.tcl >> run1.tcl
