If dlya0908.tab is in sorted order by field 1, and tgpr.tab is not changing while your script is running, you might want to try:
Code:
sort -b -k2,2 tgpr.tab|join -1 1 -2 2 -a 1 -a 2 -e "NULL" -o'0,1.1,2.2' dlya0908.tab -

which, with the data shown in post #10, produces the output:
Code:
00033492482 00033492482 NULL
00033492682 00033492682 NULL
00033492702 00033492702 NULL
00076848302 00076848302 NULL
00881123792 00881123792 NULL
01130162424 01130162424 NULL
01130164254 01130164254 NULL
01130165543 01130165543 NULL
01130168864 01130168864 NULL
01635163349 01635163349 01635163349
03139822826 NULL 03139822826
49246820001 NULL 49246820001
67119603398 NULL 67119603398
67261704102 NULL 67261704102
73379268872 NULL 73379268872
7621830148 NULL 7621830148
822004599003 NULL 822004599003

Or, with just:
Code:
sort -b -k2,2 tgpr.tab|join -1 1 -2 2 -e "NULL" -o'0,1.1,2.2' dlya0908.tab -

and those same input files, you get the output:
Code:
01635163349 01635163349 01635163349

PS: Note, however, that this only works if your input files actually have tab separated fields. The sample files you have provided in this thread use sequences of spaces as field separators (not tabs).

ExtUtils::Command(3pm)					 Perl Programmers Reference Guide				    ExtUtils::Command(3pm)

NAME
ExtUtils::Command - utilities to replace common UNIX commands in Makefiles etc. SYNOPSIS
perl -MExtUtils::Command -e cat files... > destination perl -MExtUtils::Command -e mv source... destination perl -MExtUtils::Command -e cp source... destination perl -MExtUtils::Command -e touch files... perl -MExtUtils::Command -e rm_f files... perl -MExtUtils::Command -e rm_rf directories... perl -MExtUtils::Command -e mkpath directories... perl -MExtUtils::Command -e eqtime source destination perl -MExtUtils::Command -e test_f file perl -MExtUtils::Command -e test_d directory perl -MExtUtils::Command -e chmod mode files... ... DESCRIPTION
The module is used to replace common UNIX commands. In all cases the functions work from @ARGV rather than taking arguments. This makes them easier to deal with in Makefiles. Call them like this: perl -MExtUtils::Command -e some_command some files to work on and NOT like this: perl -MExtUtils::Command -e 'some_command qw(some files to work on)' For that use Shell::Command. Filenames with * and ? will be glob expanded. FUNCTIONS cat cat file ... Concatenates all files mentioned on command line to STDOUT. eqtime eqtime source destination Sets modified time of destination to that of source. rm_rf rm_rf files or directories ... Removes files and directories - recursively (even if readonly) rm_f rm_f file ... Removes files (even if readonly) touch touch file ... Makes files exist, with current timestamp mv mv source_file destination_file mv source_file source_file destination_dir Moves source to destination. Multiple sources are allowed if destination is an existing directory. Returns true if all moves succeeded, false otherwise. cp cp source_file destination_file cp source_file source_file destination_dir Copies sources to the destination. Multiple sources are allowed if destination is an existing directory. Returns true if all copies succeeded, false otherwise. chmod chmod mode files ... Sets UNIX like permissions 'mode' on all the files. e.g. 0666 mkpath mkpath directory ... Creates directories, including any parent directories. test_f test_f file Tests if a file exists. Exits with 0 if it does, 1 if it does not (ie. shell's idea of true and false). test_d test_d directory Tests if a directory exists. Exits with 0 if it does, 1 if it does not (ie. shell's idea of true and false). dos2unix dos2unix files or dirs ... Converts DOS and OS/2 linefeeds to Unix style recursively. SEE ALSO
Shell::Command which is these same functions but take arguments normally. AUTHOR
