[SOLVED] Separate lines with keys and store in different files

Separate lines with keys and store in different files

How to separate (get) the entire line related to hexadecimal number keys and the entire line for DEBUG in a text file, then store in different file, where the key is in this format: "[ uid key]"? i.e. ignore any lines that is not DEBUG.

in.txt:

  [ uid 28fd4583833] DEBUG web.Action
  [ uid 39fd5697944] DEBUG test.Action
  [ uid 56866969445] DEBUG test2.Action
  [ uid 76696944556] INFO  test4.Action
  [ uid 39fd5697944] DEBUG test7.Action
  [ uid 85483e10256] DEBUG testing.Action

The output files are named as "out" + i + ".txt", where i = 1, 2, 3, 4. i.e.

out1.txt:

  [ uid 28fd4583833] DEBUG web.Action

out2.txt:

  [ uid 39fd5697944] DEBUG test.Action
  [ uid 39fd5697944] DEBUG test7.Action

out3.txt:

  [ uid 56866969445] DEBUG test2.Action

out4.txt:

  [ uid 85483e10256] DEBUG testing.Action

I tried:

awk 'match($0, /uid ([^]]+)/, a) && /DEBUG/ {print > (a[1] ".txt")}' in.txt

Solution

If your file format is consistent as you show, you can just do:

awk '
    $4!="DEBUG" { next }
    !($3 in f) { f[$3] = "out" (++i) ".txt" }
    { print > f[$3] }
' in.txt

Or to avoid the open file issue mentioned in the comment:

awk '
    $4!="DEBUG" { next }
    !($3 in f) { f[$3] = "out" (++i) ".txt" }
    {
        o = f[$3]
        if (o!=p && p) close(p)
        print >> o
        p = o
    }
