will help you
I want to find the position of a '\n' in a file and print out the remaining characters after \n
code :
#include <stdio.h>

long long find_first_newline_then_print(FILE *fn) {
  int ch;
  long long pos = 0;
  while ((ch = fgetc(fin)) != EOF && ch != '\n') ++pos;
  if (ch == EOF) return -1;
  while ((ch = fgetc(fin)) != EOF) fputc(ch, stdout);
  return pos + 1;
}

hop of those help? if [[ $line1=:]] is incorrect syntax in couple of ways as spaces around = are missing and backtick is used for command substitution
awk itself can handle this:
code :
awk '/./{line=$0} END{print (line ~ /\.m/)? "ok" : "no"}' file
ok

I wish did fix the issue. I am querying using SQL on a zip-code column for checking which records in the column zipcodes do not match the format using like clause. , You seem to want:
code :
select count(*)
from zipcode_table
where zipcode_column like '%-%' and          -- has a hyphen
      zipcode_column not like '_____-____';  -- but not in the right place
where zipcode_column like '%-%' and             -- has a hyphen
      zipcode_column !~ '^[0-9]{5}-[0-9]{4}$';  -- but not in the right

I hope this helps . , Try this way:
code :
for file in filename:
    filepath=os.path.join(dir1,file)


    with open('inp.txt','r+') as f:
      texts = f.read()
      for c in bad_chars:
        texts=texts.replace(c,' ')

    #write to the file
    with open('inp.txt','w') as f:
      f.write(texts)

hope this fix your issue A file contains email addresses. Requirement is to remove words present before/after a special character & also the special character from a file. , I'd use perl or sed
