I want to take this file output:

Summary

-I- Stage                               Warnings   Errors     Comment

-I- Discovery                           3          0

-I- Lids Check                          0          0

-I- Links Check                         0          0

-I- Subnet Manager                      0          0

-I- Port Counters                       0          0

-I- Nodes Information                   16         0

-I- Speed / Width checks                0          15

-I- Virtualization                      0          0

-I- Partition Keys                      0          0

-I- Temperature Sensing                 0          0

-I- Create IBNetDiscover File           0          0

and transform it using regex to this:

“Nodes Information section has 16 Warnings and 0 Errors”

“Speed / Width checks section has 0 Warnings and 15 Errors”

etc.... for each line.

I've tried using awk, but I can't manage to get the stage section without the word "Summary" and I don't know how to properly insert the words "section has" and "errors" in the right place.

I've only made it this far:

cat file.txt | awk -F' '"{2}" '/^-I-/{print $1}'
-I- Stage
-I- Discovery
-I- Lids Check
-I- Links Check
-I- Subnet Manager
-I- Port Counters
-I- Nodes Information
-I- Speed / Width checks
-I- Virtualization
-I- Partition Keys
-I- Temperature Sensing
-I- Create IBNetDiscover File

any suggestions?

Thanks

This is one way to fix your formatting:

awk '/-I-/&&!/-I- Stage/ {
    $0=substr($0,1,62);
    s=substr($0,5,36);
    gsub(/ *$/,"",s);
    printf("\"%s section has %d Warnings and %d Errors\"\n",s,$(NF-1),$NF);
}' file.txt

• /^-I-/&&!/^-I- Stage/ - Match on lines starting with -I- but not -I- Stage.
• $0=substr($0,1,62); - Remove the Comment column from the input by only keeping the first 62 characters of the line.
• s=substr($0,5,36); - Take the substring of the whole line starting at position 5 followed by 36 characters.
• gsub(/ *$/,"",s); - In the string s, replace the trailing spaces (/ *$/) with "" (nothing)
• printf
  • \" - A literal "
  • %s - A string (which is taken from the s variable we created above)
  • %d - An integer, where $(NF-1) is the second last field and $NF is the last field.

Output:

"Discovery section has 3 Warnings and 0 Errors"
"Lids Check section has 0 Warnings and 0 Errors"
"Links Check section has 0 Warnings and 0 Errors"
"Subnet Manager section has 0 Warnings and 0 Errors"
"Port Counters section has 0 Warnings and 0 Errors"
"Nodes Information section has 16 Warnings and 0 Errors"
"Speed / Width checks section has 0 Warnings and 15 Errors"
"Virtualization section has 0 Warnings and 0 Errors"
"Partition Keys section has 0 Warnings and 0 Errors"
"Temperature Sensing section has 0 Warnings and 0 Errors"
"Create IBNetDiscover File section has 0 Warnings and 0 Errors"
