Enter a command. For example: az appconfig, fdroid, license.

comm

 
Select or reject lines common to two files. Both files must be sorted. More information: https://www.gnu.org/software/coreutils/comm.
 
  • Produce three tab-separated columns: lines only in first file, lines only in second file and common lines:
     
    comm {{file1}} {{file2}}
     
  • Print only lines common to both files:
     
    comm -12 {{file1}} {{file2}}
     
  • Print only lines common to both files, reading one file from stdin:
     
    cat {{file1}} | comm -12 - {{file2}}
     
  • Get lines only found in first file, saving the result to a third file:
     
    comm -23 {{file1}} {{file2}} > {{file1_only}}
     
  • Print lines only found in second file, when the files aren't sorted:
     
    comm -13 <(sort {{file1}}) <(sort {{file2}})
