Need a script or one-liner to purge lines from a file.
i all.
This one sounds so simple, but I can't get it to work. I need to delete lines with certain keywords from a file.
I have a file called defaultRules, with keywords:
Code:
IPSEC_AH
IKE_UDP
IPMP_TEST_IFACE2
Then, I have another file called rules.txt with some rules:
Code:
'344.','IPSEC_ESP','','','','','1.','0.','0.','0.','0.','5.','1.','Allow IPSec ESP Packets on all IP interfaces'
'345.','IPSEC_AH','','','','','1.','0.','0.','0.','0.','6.','1.','Allow IPSec AH Packets on all IP interfaces'
'346.','IKE_TCP','','','','','1.','500.','0.','0.','0.','3.','1.','Allow IKE Negotiation on all IP interfaces'
'347.','IKE_UDP','','','','','1.','500.','0.','0.','0.','2.','1.','Allow IKE Negotiation on all IP interfaces'
'348.','CLUSTER_IC_NODE1','clusternode1-priv','','','','1.','0.','0.','0.','0.','4.','1.','Allow cluster inter-connect packets from node 1'
'349.','CLUSTER_IC_NODE2','clusternode2-priv','','','','1.','0.','0.','0.','0.','4.','1.','Allow cluster inter-connect packets from node 2'
'350.','ICMP_NODE_IP','ipmp_node_alias','','','','1.','0.','0.','0.','0.','1.','1.','Allow ICMP to Node IP'
'351.','ICMP_BMS','ipmp_bms','','','','1.','0.','0.','0.','0.','1.','1.','Allow ICMP to BMS IP'
'352.','IPMP_TEST_IFACE1','ipmp_test_alias_1','','','','1.','0.','0.','0.','0.','1.','1.','Allow IPMP Test Packets on 1st test interface'
'353.','IPMP_TEST_IFACE2','ipmp_test_alias_2','','','','1.','0.','0.','0.','0.','1.','1.','Allow IPMP Test Packets on 2nd test interface'
The objective is to remove all lines in rules.txt that contain the keywords in defaultRules, so I tried this by first renaming the keywords to 'unused' and then removing all lines that contain 'unused':
Code:
for a in `cat defaultRules` ; do sed -e 's/$a/unused/' rules.txt | grep -v unused > rules.out ; done
It did nothing, rules.txt and rules.out are identical.

Greetings fellow scripters.
I find myself editing multiple files, sometimes with the same bits of information. My bash script, a changelog, and a plist file (OS X). Once I realized this, I thought why not script part of this process (and so it begins). In any case, I've solved several of the... (1 Reply)

vxusertemplate - create and administer user templates
SYNOPSIS
vxusertemplate -d file [-f] create [template [template ...]]
vxusertemplate [-f] create template_name
[description=description] [rules=rules]
[capability=capability(var=value,...)[,capability...]]
vxusertemplate delete template
vxusertemplate help [keywords | options | attributes]
vxusertemplate list
vxusertemplate print template [template ... ]
DESCRIPTION
The vxusertemplate utility provides a command line interface for the creation and administration of user-defined or user templates that may
be used with the Veritas Intelligent Storage Provisioning (ISP) feature of Veritas Volume Manager (VxVM).
The operations that can be performed by vxusertemplate are selected by specifying the appropriate keyword on the command line. See the KEY-
WORDS section for a description of the available operations.
KEYWORDS
create Creates one or more user templates, whose definitions can be read from a definitions file or entered on the command line.
delete Deletes a user template.
help Displays information on usage, keywords, options and attributes.
list Lists all user templates.
print Prints detailed information about one or more user templates.
OPTIONS -d file Specifies a file that contains user template definitions
-f Forces an operation that is not usually allowed by vxusertemplate. This option must be specified if the user template definition
differs from the existing definition in the configuration database.
EXAMPLES
Create the user templates ut1, ut2 and ut3 from the definitions in the file ut1.txt:
vxusertemplate -d ut1.txt create ut1,ut2,ut3
Delete the user template myreliabletemplate:
vxusertemplate delete myreliabletemplate
List all user templates:
vxusertemplate list
Print details of the user template mytemplate:
vxusertemplate print mytemplate
EXIT STATUS
The vxusertemplate utility exits with a non-zero status if the attempted operation fails. A non-zero exit code is not a complete indicator
of the problems encountered, but rather denotes the first condition that prevented further execution of the utility.
