http://www.unix.com – Hi everyone, Looking at writing another awk program here to find a pattern on a text file. If patterns aren't found I want the awk program to exit and then bash to file a failure log on the local machine. Then later a management framework we have in place will read if that failure log file exists and flag the computer as being failed in our database. I am pretty good with my bash skills but awk and sed still hang me up from time to time and I cannot wrap my head around this one so figure I'd ask the gurus here, as I am probably just being an idiot on how this works. Here is an example: (HowTos)

HI Guys , Using UNIX ,I intend to check with correct file pattern Access_file_Record.YYYYMM in path /tmp

If the file exist in correct format come out from code .

If not found check with different file patterns for same month period YYYYMM ( Like Access_file_Record_YYYYMM.txt or Access_file_Record_.YYYYMM)

Any different pattern file should be renamed to expected file Access_file_Record.YYYYMM

I have a question on pattern matching. I have a file with multiple patterns in it, say pattern.txt

Locus3039v1rpkm6.85 Locus3041v1rpkm6.84 Locus3042v1rpkm6.84

Locus3039v1rpkm6.85 gi|350401309|ref|XM_003486067.1| 0 10 85 328 253 8e-12 78.8 Locus3039v1rpkm6.85 gi|350401301|ref|XM_003486066.1| 0 10 85 566 491 8e-12 78.8 Locus3039v1rpkm6.8

Hi All,

i'm writing a script where i have to grep for a pattern and the 3 lines after the pattern and comment them out.

Note that i have to do this for multiple files, i am able to grep the pattern and the next 3 lines but since solaris does not recognize the -i option, i was wondering if there was any workaround.
