This is what I came up with so far, thank you for the hints:
Code:
workdir='/tmp'
iso_name='install65.iso'
sha_file='SHA256'
file = open(workdir + '/' + sha_file, 'r')
for lines in file:
values = [x.strip('()') for x in lines.split()]
#print(values)
if iso_name == values[1]:
print('file found')
if computed_sum == values[-1]:
print('hash OK')
print(values[-1])
else:
print('hash NOT OK')
print(values[-1])
exit(1)
else:
print('file NOT found')
file.close()
But I'm having a hard time understanding how I can search for one string (ex. iso name) and if found, use the same line and check for another string (hash sum).
The result of the code above is this;
Code:
38d1f8cadd502f1c27bf05c5abde6cc505dd28f3f34f8a941048ff9a54f9f608
file NOT found

I spoke too soon.
I came up with this:
Code:
def check_sha256(block_size=65536):
# fetch_sha256()
sha256 = hashlib.sha256()
with open(workdir + "/" + iso_name, 'rb') as f:
for block in iter(lambda: f.read(block_size), b''):
sha256.update(block)
computed_sum = sha256.hexdigest()
file = open(workdir + '/' + sha_file, 'r')
for lines in file:
values = [x.strip('()') for x in lines.split()]
if iso_name in values[1]:
if computed_sum in values[-1]:
print('SHA256: OK')
break
else:
print('SHA256: NOT OK. Exiting... ')
exit(1)
file.close()
It works fine from what I can see but any pointers on improvements would be welcomed!
The following find command works on the Korn Shell command line:
find . \( ! -name . -prune \) -type f -name "*.txt" -mtime +100
In the particular directory I'm in, the above find will list correctly the three text files that exist that haven't been modified in over 100 days:

ls -laR | grep "^-" | awk '{print $9}'| grep "$.txt"
It should return the list of file .txt
It's important to search .txt at the end of the line, becouse some file name have "txt" in their name but have other extensions (13 Replies)
I have many Gaussian output files, which contain a string start from "HF=" but follws the different values. I'm trying to get this exact string from these txt files.

env
ENV(1) BSD General Commands Manual ENV(1)NAME
env -- set and print environment
SYNOPSIS
env [-i] [name=value ...] [utility [argument ...]]
DESCRIPTION
env executes utility after modifying the environment as specified on the command line. The option name=value specifies an environmental
variable, name, with a value of value. The option '-i' causes env to completely ignore the environment it inherits.
If no utility is specified, env prints out the names and values of the variables in the environment, with one name=value pair per line.
EXIT STATUS
env exits with one of the following values:
0 utility was invoked and completed successfully. In this case the exit code is returned by the utility itself, not env. If no util-
ity was specified, then env completed successfully and returned the exit code itself.
1 An invalid command line option was passed to env.
1-125 utility was invoked, but failed in some way; see its manual page for more information. In this case the exit code is returned by the
utility itself, not env.
126 utility was found, but could not be invoked.
127 utility could not be found.
COMPATIBILITY
The historic - option has been deprecated but is still supported in this implementation.
SEE ALSO execvp(3), environ(7)STANDARDS
The env utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
BUGS
env doesn't handle commands with equal (``='') signs in their names, for obvious reasons.
