    JIRA-31327
    Update pbr-company-article-hero.jsp

I want to grep the Jira Id and find the commit Id for the respective grep. It is much simpler in Linux

git log | grep 32468 -B4 | awk '{print $2}'

But unfortunately -B switch is not supported in AIX for grep.

Any help would be appreciated

Use --grep option and --format=%H to print the commit hash:

git log --grep 'JIRA-32468' --format=%H

Something like with awk can do the work:

awk '/commit/{a=$2} $1 ~ "JIRA" {split($0,b,"-"); print a,b[2]}' input_file
