Dateinamen auffinden

?      # Genau ein beliebiges Zeichen
*      # Beliebig viele (auch 0) beliebige Zeichen
[def]  # Eines der Zeichen

Sortierte Dateien vergleichen

Inhalte beider Dateien anzeigen: 

cat Datei_1.txt # sollte sortiert sein

cat Datei_2.txt # sollte sortiert sein

drei-beide
eins-1
fünf  -1
fünf-beide
zwei-1
 
acht-2
drei-beide
fünf-beide
sechs-2
zweilerlei-2
zweitens-2


Standardmäßige Ausgabe: 

comm Datei_1.txt Datei_2.txt # es werden 3 Spalten ausgegeben

        acht-2
                drei-beide
eins-1
fünf  -1
                fünf-beide
        sechs-2
zwei-1
        zweilerlei-2
        zweitens-2

Es bedeuten:

  • Spalte 1: Ergebnis einzig aus Datei_1.txt
  • Spalte 2: Ergebnis einzig aus Datei_2.txt
  • Spalte 3: Ergebnis aus beiden Dateien

Das Kommando comm kann nun diese drei Ausgabespalten vermittels Option unterdrücken:

  • comm -1 unterdrücke Ausgabespalte 1 (Ergebnis übrig: Datei_2 + beide)
  • comm -12 unterdrücke Ausgabespalten 1 + 2 (Ergebnis übrig: aus beiden)
  • comm -13 unterdrücke Ausgabespalten 1 + 3 (Ergebnis übrig: Einziges aus Datei_2)
  • usw.


comm -23 Datei_1.txt Datei_2.txt 
# unterdrücke Ausgabespalte 2 + 3, erübrige Spalte 1, ergibt Einziges aus Datei_1

eins-1
fünf  -1
zwei-1
comm -13 Datei_1.txt Datei_2.txt 
# unterdrücke Ausgabespalte 1 + 3, erübrige Spalte 2, ergibt Einziges aus Datei_2

acht-2
sechs-2
zweilerlei-2
zweitens-2
comm -12 Datei_1.txt Datei_2.txt 
# unterdrücke Ausgabespalte 1 + 2, erübrige Spalte 3, ergibt aus beiderlei: Datei_1 und Datei_2

Compare Two URL Lists

Assume to have two lists of URLs, one old and one new, and you want to get only those URLs that are actually new compared to the old list. The following example asumes to have CSV (comma separated values) or TSV (tab separated values) and tries to extract the very URL, regardless of any text after the URL.

For this we use command:
comm ‹-options› oldlist_sorted comparelist_sorted or
comm ‹-options› file_1_sorted file_2_sorted and this results in 3 output columns: 

column-1         column-2        column-3
only-in-file_1
                 only-in-file_2
                                 in-file_1-and-2

… so using command comm you can now suppress one or two of these three output columns using the option:

  • comm -1 suppress output column 1 (results left: col 2 and 3, i.e. only-of-file_2 + both of in file_1-and-2)
  • comm -12 suppress output columns 1 + 2 (results left: col 3, i.e. from both of in file_1-and-2)
  • comm -13 suppress output columns 1 + 3 (results left: col 2, i.e. results only of in file_2)
  • comm -23 suppress output columns 2 + 3 (results left: col 1, i.e. results only of in file_1)
  • aso.

sort -t '/' -k3.1b urilist_JACQ_20220815_todo_sorted.tsv # sort by (t)able-field-character “/” 
  # -k*3*. 1 b  → set (k)ey field to sort after field 3, and from this position 
  # -k 3 .*1*b  → start sorting from the very 1st character to line end as being relevant for sorting
  # -k 3 . 1*b* → ignore (b)lanks
  sort --debug -t '/' -k3.1b urilist_JACQ_20220815_todo_sorted.tsv | head -n 6 # show what it is sorting actually

These data results have also missing values, the point is to extract .head.vars and use those values in the variable $fields to query all values out of .results.bindings[].[].value, the rest is getting a nice looking: 

# table head (and adding an index column)
cat institutionID_20220808.json  | jq --raw-output '.head.vars | @tsv' | sed --regexp-extended 's@^@| # | @; s@$@ |@; s@[\t]@ | @g; h; s@[^|]@-@g;x;G;'

# sed: s@^@| # | @;  add index column-header | # | to line start
# sed: s@$@ |@;      append closing table row at the end |
# sed: s@[\t]@ | @g; as it has tab separated values, replace \t by | (the colums or table data cells)
# sed: h;            put this ready formatted header into hold space buffer
# sed: s@[^|]@-@g;   replace all but “|” by “-” to make the markdown header separation
# sed: x;            exchange hold space buffer (formatted 1st table row) with the markdown header separation
# sed: G;            now we have only the first table row in place and append (G) the markdown header separation by a \n 
#                    and get a nice complete table header:
