Attempting to locate a variety of similar incidents within a file.
<address DOMAIN='0x000' bus='PCOIP_USB0' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='PCOIP_USB1' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='PCOIP_USB7' slot='0x00' function '0x0' />
<address type='bmu' domain='0x000' bus='PCOIP_USB9' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='PCOIP_USB4' slot='0x00' function '0x0' />
I'm attempting to simply locate any instance beginning with PCOIP_ and replace that string with 0x86
The result will look like:
<address DOMAIN='0x000' bus='0x86' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='0x86' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='0x86' slot='0x00' function '0x0' />
<address type='bmu' domain='0x000' bus='0x86' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='0x86' slot='0x00' function '0x0' />
The command I'm trying currently which handles replacing the necessary string, except it also wipes the remainder of that entire line:
sed s/PCOIP_\(.*\)/0x86/g' file
The command as is makes the file look like:
<address DOMAIN='0x000' bus='0x86
<address DOMAIN='0x000' bus='0x86
<address DOMAIN='0x000' bus='0x86
<address type='bmu' domain='0x000' bus='0x86
<address DOMAIN='0x000' bus='0x86
You can use
sed "s/PCOIP_[^']*/0x86/g" file
Here, PCOIP_[^']* matches PCOIP_ and then any zero or more chars other than a ' char. The whole match is replaced with 0x86 substring.
See an online demo:
#!/bin/bash
s="<address DOMAIN='0x000' bus='PCOIP_USB0' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='PCOIP_USB1' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='PCOIP_USB7' slot='0x00' function '0x0' />
<address type='bmu' domain='0x000' bus='PCOIP_USB9' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='PCOIP_USB4' slot='0x00' function '0x0' />"
sed "s/PCOIP_[^']*/0x86/g" <<< "$s"
Output:
<address DOMAIN='0x000' bus='0x86' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='0x86' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='0x86' slot='0x00' function '0x0' />
<address type='bmu' domain='0x000' bus='0x86' slot='0x00' function '0x0' />
<address DOMAIN='0x000' bus='0x86' slot='0x00' function '0x0' />
