Could you please advise how can one extract from the output of
find . -name "*.c" -print
only filenames in the current direcotry and not in its subdirectories?
I tried using (on Linux x86_64)
find . -name "*.c" -prune
but it is not giving correct output.
Other than prune, is it possible to pipe GREP with find to get desired output?
If you don't want to descend into subdirectories, the simple way to do this is:
Code:
ls -1 *.c
Note that in the ls option -1 that is the digit one, not the letter ell.
Or, if you just want to see how pruning would work using a basic regular expression in grep instead of a filename pattern match in the shell, use:
Code:
ls|grep '[.]c$'
If you wonder why the $ is there, try running the above command with and without the $ in a directory in which there is a file named source.cpp and a file named source.c.
If you wonder why you need [.] instead of just . in a BRE, try the command above with and without the $ and with and without the square brackets in a directory that contains the files named before and files named abc, bcd, and c.
How can i create a regular expression which can detect a new line charcter followed by a special character say * and replace these both by a string of zero length?
Eg:
Input File san.txt

In regular expressions with grep(or egrep), ^ works if we want something in starting of line..but what if we write ^^^ or ^ for pattern matching??..Hope u all r familiar with regular expressions for pattern matching.. (1 Reply)
what elements does " /^/ " match?
I did the test which indicates that it matches single lowercase character like 'a','b' etc. and '1','2' etc.
But I really confused with that. Because, "/^abc/" matches strings like "abcedf" or "abcddddee".
So, what does caret ^ really mean?
Any response... (2 Replies)

lam
LAM(1) BSD General Commands Manual LAM(1)NAME
lam -- laminate files
SYNOPSIS
lam [-f min.max] [-p min.max] [-s sepstring] [-t c] file ...
DESCRIPTION
lam copies the named files side by side onto the standard output. The n-th input lines from the input files are considered fragments of the
single long n-th output line into which they are assembled. The name ``-'' means the standard input, and may be repeated.
Normally, each option affects only the file after it. If the option letter is capitalized it affects all subsequent files until it appears
again uncapitalized. The options are described below.
-f min.max Print line fragments according to the format string min.max, where min is the minimum field width and max the maximum field
width. If min begins with a zero, zeros will be added to make up the field width, and if it begins with a '-', the fragment
will be left-adjusted within the field.
-p min.max Like -f, but pad this file's field when end-of-file is reached and other files are still active.
-s sepstring Print sepstring before printing line fragments from the next file. This option may appear after the last file.
-t c The input line terminator is c instead of a newline. The newline normally appended to each output line is omitted.
To print files simultaneously for easy viewing use pr(1).
EXAMPLES
The command
lam file1 file2 file3 file4
joins 4 files together along each line. To merge the lines from four different files use
lam file1 -S "
" file2 file3 file4
Every 2 lines of a file may be joined on one line with
lam - - < file
and a form letter with substitutions keyed by '@' can be done with
lam -t @ letter changes
