adding lines at special place in crontab
Hi ,

i export the crontab in a file (i've no root right) and i would add lines from a file at a special place and rewrite the output in an another file.

the special place is as this :

45 04 * * * /home/toto.sh > /dev/null 2>&1
#

so i would search for toto.sh and insert the lines , the line after the "#"

as this :


45 04 * * * /home/toto.sh > /dev/null 2>&1
#
00 05 * * * /home/neslines.sh > /dev/null 2>&1
#


thanks ina dvance

Code:
$ more footab
45 04 * * * /home/other.sh > /dev/null 2>&1
#
45 04 * * * /home/toto.sh > /dev/null 2>&1
#
45 04 * * * /home/another.sh > /dev/null 2>&1
#
$ more dotab.awk
/toto.sh/ {
  print
  printf( "#\n%s\n#\n", "00 05 * * * /home/neslines.sh > /dev/null 2>&1" )
}
{ print }
$ nawk -f dotab.awk footab
45 04 * * * /home/other.sh > /dev/null 2>&1
#
45 04 * * * /home/toto.sh > /dev/null 2>&1
#
00 05 * * * /home/neslines.sh > /dev/null 2>&1
#
45 04 * * * /home/toto.sh > /dev/null 2>&1
#
45 04 * * * /home/another.sh > /dev/null 2>&1
#

The reinsertion of the "toto.sh" line was sloppiness on my part - apologies Smilie
Code:
$ more footab
45 04 * * * /home/other.sh > /dev/null 2>&1
#
45 04 * * * /home/toto.sh > /dev/null 2>&1
#
45 04 * * * /home/another.sh > /dev/null 2>&1
#
$ more dotab.awk
{
  if ( $0 ~ /toto.sh/ ) {
    print
    printf( "#\n%s\n",
      "00 05 * * * /home/neslines.sh > /dev/null 2>&1" )
  } else {
    print
  }
}
$ awk -f dotab.awk footab
45 04 * * * /home/other.sh > /dev/null 2>&1
#
45 04 * * * /home/toto.sh > /dev/null 2>&1
#
00 05 * * * /home/neslines.sh > /dev/null 2>&1
#
45 04 * * * /home/another.sh > /dev/null 2>&1
#

Anyway, if I understand your requirements correctly, then the following Perl code will do the trick....
Code:
$ more footab
45 04 * * * /home/other.sh > /dev/null 2>&1
#
45 04 * * * /home/toto.sh > /dev/null 2>&1
#
45 04 * * * /home/another.sh > /dev/null 2>&1
#
$ more moretab
01 04 * * * /home/1.sh > /dev/null 2>&1
#
02 04 * * * /home/2.sh > /dev/null 2>&1
#
03 04 * * * /home/3.sh > /dev/null 2>&1
#
$ more dotab.pl
#!/usr/bin/perl

open( INFILE, "footab" );
@lines=<INFILE>;
close( INFILE );

foreach (@lines) {
  print $_;
  if ( $_ =~ /toto\.sh/ ) {
    $found_toto = 1;
  }
  if ( $found_toto == 1 && $_ =~ /#/ ) {
     open( MOREFILE, "moretab" );
     print $_ while( <MOREFILE> );
     close( MOREFILE );
     $found_toto = 0;
  }
}
$ ./dotab.pl
45 04 * * * /home/other.sh > /dev/null 2>&1
#
45 04 * * * /home/toto.sh > /dev/null 2>&1
#
01 04 * * * /home/1.sh > /dev/null 2>&1
#
02 04 * * * /home/2.sh > /dev/null 2>&1
#
03 04 * * * /home/3.sh > /dev/null 2>&1
#
45 04 * * * /home/another.sh > /dev/null 2>&1
#

Cheers

Could use sed...
Code:
$ cat prog.sed
/toto.sh/{n;r moretab
;}

$ sed -f prog.sed footab
45 04 * * * /home/other.sh > /dev/null 2>&1
#
45 04 * * * /home/toto.sh > /dev/null 2>&1
#
01 04 * * * /home/1.sh > /dev/null 2>&1
#
02 04 * * * /home/2.sh > /dev/null 2>&1
#
03 04 * * * /home/3.sh > /dev/null 2>&1
#
45 04 * * * /home/another.sh > /dev/null 2>&1
#
