All,
I have a text file with several entries like below:
personname
personname.domain.com
I know there is a way to use vi to remove only the personname.domain.com line. Can someone help? I believe that it involves /s/g/ something...I just can't remember the exact syntax.
Thanks (2 Replies)

CDBS-EDIT-PATCH(1) CDBS Documentation CDBS-EDIT-PATCH(1) NAME
cdbs-edit-patch - create or edit a CDBS simple-patchsys.mk patch SYNOPSIS
cdbs-edit-patch patchname DESCRIPTION
cdbs-edit-patch creates or edits patches for use by the CDBS simple-patchsys.mk patch system. For more information about CDBS please see the documentation under /usr/share/doc/cdbs/. When patchname exists, cdbs-edit-patch will set up a temporary working source tree, apply all patches up to and including patchname in lex- icographic order, and spawn an interactive shell for the developer. The developer can then edit files in this working tree. When the developer is done and exits the shell, cdbs-edit-patch updates patchname to reflect the changes made. To abort the process from the inter- active shell, exit with a nonzero exit value. When patchname does not exist, cdbs-edit-patch will assume that a new patch should be created. As with the above scenario, cdbs-edit-patch will first create a temporary working source tree and apply all patches up to the new patch in lexicographic order. When the shell is quit, cdbs-edit-patch will create patchname. AUTHOR
