Hello emily,

Could you please try following code and let me know if this helps.

awk -vs="'" -vs1="infile=[" -vs2="]" -vs3="infile.append(" -vs4=")" '(NR==1){print s1 s $2 s s2} (NR>1){print s3 s $2 s s4}'  Input_file

Output will be as follows.

infile=['/abcd/directory/sub_directory/Samsung/150206_135953/0000/L1ITMBLT_54.root']
infile.append('/abcd/directory/sub_directory/Samsung/150206_135953/0000/L1ITMBLT_93.root')
infile.append('/abcd/directory/sub_directory/Samsung/150206_135953/0000/L1ITMBLT_74.root')
infile.append('/abcd/directory/sub_directory/Samsung/150206_135953/0000/L1ITMBLT_171.root')
infile.append('/abcd/directory/sub_directory/Samsung/150206_135953/0000/L1ITMBLT_112.root')
infile.append('/abcd/directory/sub_directory/Samsung/150206_135953/0000/L1ITMBLT_107.root')
infile.append('/abcd/directory/sub_directory/Samsung/150206_135953/0000/L1ITMBLT_18.root')

NOTE: Considering your Input_file doesn't have spaces in starting.

Thanks,
