How to get character string out from file in UNIX -


i have file on unix has line special characters pure character string. special character .,$%&*()-@. sample below

i want pure character string lines out of file. have way read each line , compare each character alphabets if file big consume lot of time.

any better approach or suggestions?

your best bet grep utility.

grep -i '^[a-z]\+$' file.txt

specifically, we're doing case-insensitive search (-i) lines contain characters [a-z], , characters start (^) finish ($).

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 ...
