The Linux commands Grep commands for analyzing timing reports

Grep commands

1. Gives you the number of paths which has the same endpoints.

>  grep "Endpoint: hierarchical_top_name\/instance_name\/cellname_\[0\]" filename_timing.rpt | wc 

---

2. The below command is used to search for a specific pattern in files. -R in option allows for recursive search. You can use -i for disabling case sensitive.

> grep -R "Word" /path

---

3. To find specific different startpoints associated with the same endpoint. Basically,

- Z gives us a line before the pattern. -u gives us unique.

> grep "Endpoint: hierarchical_top_name\/instance_name\/cellname_\[0\]" -Z2 | grep "Startpoint:" -u 

---

4. To find Startpoint except "some specific startpoint" associated with Endpoint. We use -v to exclude.

> grep "Endpoint: hierarchical_top_name\/instance_name\/cellname_\[0\]" -Z2 | grep "Startpoint:hierarchical_top_name\/instance_name\/cellname_\[4\] " -v
