Top Forums Shell Programming and Scripting Delete 40 lines after every 24 lines from a file Post 302886833 by Scrutinizer on Tuesday 4th of February 2014 01:17:19 AM

Delete lines 34-74 then 94-134 then 154 -174 and so on, you mean? And first 14 lines?
Then 15-33 would remain and 75-93 and 135-153, i.e. 19 lines every time...
Try:
Code:
awk '!((NR-s)%m),!((NR-s-p+1)%m)' s=15 m=60 p=19 file

You get the idea. I used parameters so you can twiddle the knobs..

NAME
isprint -- printing character test (space character inclusive) LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <ctype.h> int isprint(int c); DESCRIPTION
The isprint() function tests for any printing character, including space (' '). The value of the argument must be representable as an unsigned char or the value of EOF. In the ASCII character set, this includes the following characters (preceded by their numeric values, in octal): 040 sp 041 ``!'' 042 ``"'' 043 ``#'' 044 ``$'' 045 ``%'' 046 ``&'' 047 ``''' 050 ``('' 051 ``)'' 052 ``*'' 053 ``+'' 054 ``,'' 055 ``-'' 056 ``.'' 057 ``/'' 060 ``0'' 061 ``1'' 062 ``2'' 063 ``3'' 064 ``4'' 065 ``5'' 066 ``6'' 067 ``7'' 070 ``8'' 071 ``9'' 072 ``:'' 073 ``;'' 074 ``<'' 075 ``='' 076 ``>'' 077 ``?'' 100 ``@'' 101 ``A'' 102 ``B'' 103 ``C'' 104 ``D'' 105 ``E'' 106 ``F'' 107 ``G'' 110 ``H'' 111 ``I'' 112 ``J'' 113 ``K'' 114 ``L'' 115 ``M'' 116 ``N'' 117 ``O'' 120 ``P'' 121 ``Q'' 122 ``R'' 123 ``S'' 124 ``T'' 125 ``U'' 126 ``V'' 127 ``W'' 130 ``X'' 131 ``Y'' 132 ``Z'' 133 ``['' 134 ``'' 135 ``]'' 136 ``^'' 137 ``_'' 140 ```'' 141 ``a'' 142 ``b'' 143 ``c'' 144 ``d'' 145 ``e'' 146 ``f'' 147 ``g'' 150 ``h'' 151 ``i'' 152 ``j'' 153 ``k'' 154 ``l'' 155 ``m'' 156 ``n'' 157 ``o'' 160 ``p'' 161 ``q'' 162 ``r'' 163 ``s'' 164 ``t'' 165 ``u'' 166 ``v'' 167 ``w'' 170 ``x'' 171 ``y'' 172 ``z'' 173 ``{'' 174 ``|'' 175 ``}'' 176 ``~'' RETURN VALUES
The isprint() function returns zero if the character tests false and returns non-zero if the character tests true. COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered obsolete and may not be supported in future releases. The iswprint() function should be used instead. SEE ALSO
ctype(3), isalnum_l(3), iswprint(3), ascii(7) STANDARDS
The isprint() function conforms to ISO/IEC 9899:1990 (``ISO C90''). BSD
