I want to comment certain lines in fstab using sed command. The following are the lines I need to comment:
172.0.0.1:/export/project/common /nfs/share nfs4 rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp
172.0.0.1:/export/project/share1 /nfs/shares1 nfs4 rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp
I tried using this command but it didn't work:
sed -i '/172.0.0.1:/export/project/common /nfs/share nfs4 rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp /s/^/#/' /etc/fstab_test
sed -i '/172.0.0.1:/export/project/share1 /nfs/shares1 nfs4 rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp /s/^/#/' /etc/fstab_test
linux sed fstab

Try this,
sed -e '/[/]/common s/^/#/' /etc/fstabsed -e '/[/]/share1 s/^/#/' /etc/fstab
Specifying this /[/]common/ will select only lines that contain /common.
If this works then replace -e with -i for executing the changing into the file.
You can do this with awk
awk '/[/]common/$0="#"$0 1' /etc/fstab >/etc/fstab.tmp && mv /etc/fstab.tmp /etc/fstab
awk '/[/]share1/$0="#"$0 1' /etc/fstab >/etc/fstab.tmp && mv /etc/fstab.tmp /etc/fstab
Specifying this /[/]common/ $0="#"$0 will chose those lines containing /common and place a # at the beginning of the line.

if the full paths (either NFS remote or local mount point) are the only unique things on a line, then you'll have to use one of them. and remember to escape all/s as/.

Try this,
sed -e '/[/]/common s/^/#/' /etc/fstabsed -e '/[/]/share1 s/^/#/' /etc/fstab
Specifying this /[/]common/ will select only lines that contain /common.
If this works then replace -e with -i for executing the changing into the file.
You can do this with awk
awk '/[/]common/$0="#"$0 1' /etc/fstab >/etc/fstab.tmp && mv /etc/fstab.tmp /etc/fstab
awk '/[/]share1/$0="#"$0 1' /etc/fstab >/etc/fstab.tmp && mv /etc/fstab.tmp /etc/fstab
Specifying this /[/]common/ $0="#"$0 will chose those lines containing /common and place a # at the beginning of the line.
