    copied!<p>I have a log file that contains a lot of text, some of it is useless. In this log there are some lines that are important for me. The pattern for those lines are:</p> <pre><code> 0x00000001 (NEEDED) Shared library: [libm.so.6] 0x00000001 (NEEDED) Shared library: [libc.so.6] 0x00000001 (NEEDED) Shared library: [ld.so.1] 0x00000001 (NEEDED) Shared library: [libgcc_s.so.1] </code></pre> <p>The NEEDED keyword could be found on all lines that are important for me. The keyword between [] is the one important for me. I need to create a list of all those strings, without repeating them.</p> <p>I've done this on Python, but looks like on the machine I want to run the script there is no Python available, so I need to rework the script in bash. I know only basic stuff in bash and I'm not able to find a solution for my problem.</p> <p>The Python script I've used is:</p> <pre><code>import sys import re def testForKeyword(keyword, line): findStuff = re.compile(r"\b%s\b" % keyword, \ flags=re.IGNORECASE) if findStuff.search(line): return True else: return False # Get filename argument if len(sys.argv) != 2: print("USAGE: python libraryParser.py &lt;log_file.log&gt;") sys.exit(-1) file = open(sys.argv[1], "r") sharedLibraries = [] for line in file: if testForKeyword("NEEDED", line): libraryNameStart = line.find("[") + 1 libraryNameFinish = line.find("]") libraryName = line[libraryNameStart:libraryNameFinish] # No duplicates, only add if it does not exist try: sharedLibraries.index(libraryName) except ValueError: sharedLibraries.append(libraryName) for library in sharedLibraries: print(library) </code></pre> <p>Can you please help me solving this issue? Thanks in advance.</p>
