Sed a variable which has - character in it
Hi

Because my GR_RESOURCE_DIR variable has - character in it the sed doesn't work. Could you please advise ?

[root@skynet conf]# cat globalrelay.ini
[Basic Configuration]
ResourceDIR=/app-nfs/meta/relay

[root@skynet bianca]# cat xac.sh
#!/bin/bash
#XAC_INSTALL_PATH=/usr/XenonAdministrationCenter
GR_RESOURCE_DIR=new-app

sed -e "s-\(^ResourceDIR=\)\([^#]*\)-\1${GR_RESOURCE_DIR}-" aaaa > bbbb

[root@skynet bianca]# ./xac.sh
sed: -e expression #1, char 36: unknown option to `s'

Thanks,
Bianca

What exactly are you trying to do here?

Change "ResourceDIR=/app-nfs/meta/relay" to "ResourceDIR=new-app?
Change "ResourceDIR=/app-nfs/meta/relay" to "ResourceDIR=/new-app/meta/relay?

I want to replace everythig after ResourceDIR= with the variable read during install.

I want to specify that another parameter that need to be replace is
MountFolderLive=/live/, /app-nfs/meta/relay
and here only /app-nfs/meta/relay to be replaced with the variable read.

Thanks
Bianca

Try the following:

Code:
sed -e "s|\(^ResourceDIR=\)\([0-9a-zA-Z\/\-]*$\)|\1${GR_RESOURCE_DIR}|" infile > outfile

Hi

This works for my first parameter ResourceDIR but not for the second one:
[root@skynet bianca]# cat aaaa
[Basic Configuration]
ResourceDIR=/app-nfs/meta/relay
MountFolderLive=/live/, /app-nfs/meta/live

For the second one /app-nfs/meta/live should be replaced with the read variable .

sed -e "s|\(^MountFolderLive=/live/,\)\([0-9a-zA-Z\/\-]*$\)|\1${GS_MOUNT_FOLDER_META}|" aaaa > bbbb

This doesn't work for this parameter.

Thanks,
Bianca

What is this "read variable"? Please give example of expected output.

Nobody can help you unless you are more precise with your requests for help.

[root@skynet bianca]# cat aaaa
[Basic Configuration]
ResourceDIR=/app-nfs/meta/relay
MountFolderLive=/live/, /xac-nfs/meta/live

[root@skynet bianca]# cat xac.sh
#!/bin/bash
GR_RESOURCE_DIR=/new-app/meta/relay
GS_MOUNT_FOLDER_META=/new-app/meta/live
> bbbb
cat aaaa

sed -e "s|\(^ResourceDIR=\)\([0-9a-zA-Z\/\-]*$\)|\1${GR_RESOURCE_DIR}|" \
-e "s|\(^MountFolderLive=/live/,\)\([0-9a-zA-Z\/\-]*$\)|\1${GS_MOUNT_FOLDER_META}|" aaaa > bbbb

cat bbbb

Expected output in bbbb file:
[Basic Configuration]
ResourceDIR=/new-app/meta/relay
MountFolderLive=/live/, /new-app/meta/live

Thanks,
Bianca
