Greetings.
I am struggling with a shell script to make my life simpler, with a number of practical ways in which it could be used. I want to take a standard text file, and pull the 'n'th word from each line such as the first word from a text file.
I'm struggling to see how each line can be... (5 Replies)
Hi, I am a newb as far as shell scripting and SED goes so bear with me on this one.
I want to basically append to each line in a file a delimiter character and the line's line number e.g
Change the file from :-
aaaaaa
bbbbbb
cccccc
to:-
aaaaaa;1
bbbbbb;2
cccccc;3

Hi all,
I have to append every alternate line after its previous line. For example if my file has following contents
line 1: unix is an OS
line 2: it is open source
line 3: it supports shell programming
line 4: we can write shell scripts
Required output should be
line1: unix is an OS it is... (4 Replies)
I know this has been asked before but I just can't parse the syntax as explained. I have a set of files that has user information spread out over two lines that I wish to merge into one:

Hi Experts,
Am relatively new to shell programming so would appreciate some help in this regard.
I am looking at reading from a file, line by line, picking the first word of each line and appending it to the end of the line.
Any suggestions?

OD(1) FSF OD(1)NAME
od - dump files in octal and other formats
SYNOPSIS
od [OPTION]... [FILE]...
od --traditional [FILE] [[+]OFFSET [[+]LABEL]]
DESCRIPTION
Write an unambiguous representation, octal bytes by default, of FILE to standard output. With more than one FILE argument, concatenate
them in the listed order to form the input. With no FILE, or when FILE is -, read standard input.
All arguments to long options are mandatory for short options.
-A, --address-radix=RADIX
decide how file offsets are printed
-j, --skip-bytes=BYTES
skip BYTES input bytes first
-N, --read-bytes=BYTES
limit dump to BYTES input bytes
-s, --strings[=BYTES]
output strings of at least BYTES graphic chars
-t, --format=TYPE
select output format or formats
-v, --output-duplicates
do not use * to mark line suppression
-w, --width[=BYTES]
output BYTES bytes per output line
--traditional
accept arguments in traditional form
--help display this help and exit
--version
output version information and exit
Traditional format specifications may be intermixed; they accumulate:
-a same as -t a, select named characters
-b same as -t oC, select octal bytes
-c same as -t c, select ASCII characters or backslash escapes
-d same as -t u2, select unsigned decimal shorts
-f same as -t fF, select floats
-h same as -t x2, select hexadecimal shorts
-i same as -t d2, select decimal shorts
-l same as -t d4, select decimal longs
-o same as -t o2, select octal shorts
-x same as -t x2, select hexadecimal shorts
For older syntax (second call format), OFFSET means -j OFFSET. LABEL is the pseudo-address at first byte printed, incremented when dump is
progressing. For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal, suffixes may be . for octal and b for multiply by 512.
TYPE is made up of one or more of these specifications:
a named character
c ASCII character or backslash escape
d[SIZE]
signed decimal, SIZE bytes per integer
f[SIZE]
floating point, SIZE bytes per integer
o[SIZE]
octal, SIZE bytes per integer
u[SIZE]
unsigned decimal, SIZE bytes per integer
x[SIZE]
hexadecimal, SIZE bytes per integer
SIZE is a number. For TYPE in doux, SIZE may also be C for sizeof(char), S for sizeof(short), I for sizeof(int) or L for sizeof(long). If
TYPE is f, SIZE may also be F for sizeof(float), D for sizeof(double) or L for sizeof(long double).
RADIX is d for decimal, o for octal, x for hexadecimal or n for none. BYTES is hexadecimal with 0x or 0X prefix, it is multiplied by 512
with b suffix, by 1024 with k and by 1048576 with m. Adding a z suffix to any type adds a display of printable characters to the end of
each line of output. --string without a number implies 3. --width without a number implies 32. By default, od uses -A o -t d2 -w 16.
