Looking for an awk command to print strings only if substring is missing
I have a file that I need to find each interface that has move-group on the interface line and print this line if the lines under the interface does Not have "filter-shared 14".
Example file:
Code:
interface 1/1/1/0 move-group
decription one one one zero
no shut
filter-shared 14
accounting-policy 5
shared-address 0
interface 1/1/1/1 move-group
decription one one one one
no shut
accounting-policy 5
shared-address 0
interface 1/1/1/2 move-group
decription one one one two
no shut
filter-shared 14
accounting-policy 5
shared-address 0
interface 1/1/1/3 move-group
decription one one one three
no shut
accounting-policy 5
shared-address 0
interface 1/1/1/4 permanent-group
decription one one one four
no shut
accounting-policy 5
shared-address 0
I only wish to print out the interface line that does have "filter-shared 14" under it.
So the output would look like this:
Stash each interface line in a variable a, and 0 in another b, and as your seaarch forward, look for filter-shared 14, and if you find it, st the second var b to 1, and at the next interface line or EOF if b still a zero, print the stash a before stashing the new interface line. So, in code the last bit comes first!
Thank you Scrutinizer, that works. But it skips the first line of the file if there is a match. I think it's because x is empty until after the first line.
Note that there are two parts. The first puts empty lines around the records, the "x" is an empty variable, so that an empty line gets printed before that start of each record.
This then enables the second awk to use RS=, a special value so that records can be separated by blank lines and thus become multi-line records. So for example the first record becomes:
Code:
interface 1/1/1/0 move-group
decription one one one zero
no shut
filter-shared 14
accounting-policy 5
shared-address 0
Because the fields separator FS is set to \n, the first field ($1) is equal to the first line of such a multiline record..
I have two files and desire to use the strings from $1 of file 1 (file1.txt) as search criteria to find matches in $2 of file 2 (file2.txt). If matches are found I want to output the entire line of file 2 (file2.txt) followed by fields $2-$11 of file 1 (file1.txt). I can find the matches, I cannot... (7 Replies)
The below awk in bold will look for the ids in file1 in $2 of file2 and if they match print the line in file2. If an id is missing or not found in file2 (like BMPR2 in line4 of file1) I can not figure out how to add it to them to the lines in the output as missing in $3 following the same format....
