regex - Awk/sed solution for replacing/prepending subset of lines in between 2 patterns -


i use sed/awk edit/prepend specific lines in between 2 patterns (east_40_1_ep00 &arr , #pchan 5). here block of text:

   east_40_1_ep00 &arr{            # template 6-channel units @ brtt                              #       nothing specified means use global parameters             pchan_map &arr{         #these map q330 physical channels seed net-sta-chan-loc codes             #       pchan   net_sta_chan[_loc]      calib   calper  segtype                       0       $dlnet_$dlsta_bhz_00    $db                      1       $dlnet_$dlsta_bhn_00    $db                      2       $dlnet_$dlsta_bhe_00    $db                      0       $dlnet_$dlsta_lhz_00    $db                      1       $dlnet_$dlsta_lhn_00    $db                      2       $dlnet_$dlsta_lhe_00    $db                      3       $dlnet_$dlsta_bhz_01    $db                      4       $dlnet_$dlsta_bhn_01    $db                      5       $dlnet_$dlsta_bhe_01    $db                      3       $dlnet_$dlsta_lhz_01    $db                      4       $dlnet_$dlsta_lhn_01    $db                      5       $dlnet_$dlsta_lhe_01    $db             }             acq_matrix &tbl{                                # acquisition matrix             #       str0 str1 str2 str3 str4 str5 str6 str7              #       1    10   20   40   50   100  200                       m1   0    0    m40  0    0    0    0  # pchan 0                     m1   0    0    m40  0    0    0    0  # pchan 1                     m1   0    0    m40  0    0    0    0  # pchan 2                     m1   0    0    m40  0    0    0    0  # pchan 3                     m1   0    0    m40  0    0    0    0  # pchan 4                     m1   0    0    m40  0    0    0    0  # pchan 5             }     }

i add comment tags "#' lines 11-16, , 24,26 using sed/awk, block of text looks like:

  east_40_1_ep00 &arr{            # template 6-channel units @ brtt                              #       nothing specified means use global parameters             pchan_map &arr{         #these map q330 physical channels seed net-sta-chan-loc codes             #       pchan   net_sta_chan[_loc]      calib   calper  segtype                       0       $dlnet_$dlsta_bhz_00    $db                      1       $dlnet_$dlsta_bhn_00    $db                      2       $dlnet_$dlsta_bhe_00    $db                      0       $dlnet_$dlsta_lhz_00    $db                      1       $dlnet_$dlsta_lhn_00    $db                      2       $dlnet_$dlsta_lhe_00    $db             #         3       $dlnet_$dlsta_bhz_01    $db             #         4       $dlnet_$dlsta_bhn_01    $db             #         5       $dlnet_$dlsta_bhe_01    $db             #         3       $dlnet_$dlsta_lhz_01    $db             #         4       $dlnet_$dlsta_lhn_01    $db             #         5       $dlnet_$dlsta_lhe_01    $db             }             acq_matrix &tbl{                                # acquisition matrix             #       str0 str1 str2 str3 str4 str5 str6 str7              #       1    10   20   40   50   100  200                       m1   0    0    m40  0    0    0    0  # pchan 0                     m1   0    0    m40  0    0    0    0  # pchan 1                     m1   0    0    m40  0    0    0    0  # pchan 2             #        m1   0    0    m40  0    0    0    0  # pchan 3             #        m1   0    0    m40  0    0    0    0  # pchan 4             #        m1   0    0    m40  0    0    0    0  # pchan 5             }     }

i don't mind executing 2 separate commands if have to, 1 ideal. have 2 commands grab out subset lines, unsure how can modify them make edit actual file lines:

  sed -n "/east_40_1_ep00 &arr/,/#pchan 5/p" q3302orb_test.pf | sed -n '11,16p' | awk '{print "#"$0 }' file    sed -n "/east_40_1_ep00 &arr/,/#pchan 5/p" q3302orb_test.pf | sed -n '24,26p' | awk '{print "#"$0 }' file

can me out how 1) combine these commands 1 command, , 2) edit file not print out lines. i've tried using -i command in various places no luck.

thanks in advance!

#!/usr/bin/awk -f begin {   alpha[11] alpha[12] alpha[13] alpha[14] alpha[15] alpha[16]   alpha[24] alpha[26] } /east_40_1_ep00 &arr/ {   bravo = 1   charlie = nr } /#pchan 5/ {   bravo = 0 } bravo && nr-charlie+1 in alpha {   $0 = "#" $0 } 1
  1. set array of lines
  2. once start marker found, save it
  3. also save line number of start marker
  4. set stop marker
  5. between markers, if line number good, add comment
  6. print

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
