I am facing some strange problem.
I know, there is only one record in a file 'test.txt' which starts with 'X'
I ensure that with following command,
awk /^X/ test.txt | wc -l
This gives me output = '1'.
Now I take out this record out of the file, as follows :
awk /^X/ test.txt >... (1 Reply)
I have a script with a find command using xargs to copy the files found to another directory. The find command is finding the appropriate file, but it's not copying. I've checked permissions, and those are all O.K., so I'm not sure what I'm missing. Any help is greatly appreciated.

Hi!
Been working on a script and I've been having a problem. I've finally narrowed it down to this variable I'm setting:
servername=$(awk -v FS=\/ '{ print $7 } blah.txt | sed 's\/./-/g' | awk -v FS=\- '{print $1}')"
This will essentially pare down a line like this:

isgraph
ISGRAPH(3) BSD Library Functions Manual ISGRAPH(3)NAME
isgraph -- printing character test (space character exclusive)
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
isgraph(int c);
DESCRIPTION
The isgraph() function tests for any printing character except space (' ') and other locale-specific space-like characters. The value of the
argument must be representable as an unsigned char or the value of EOF.
In the ASCII character set, this includes the following characters (preceded by their numeric values, in octal):
041 ``!'' 042 ``"'' 043 ``#'' 044 ``$'' 045 ``%''
046 ``&'' 047 ``''' 050 ``('' 051 ``)'' 052 ``*''
053 ``+'' 054 ``,'' 055 ``-'' 056 ``.'' 057 ``/''
060 ``0'' 061 ``1'' 062 ``2'' 063 ``3'' 064 ``4''
065 ``5'' 066 ``6'' 067 ``7'' 070 ``8'' 071 ``9''
072 ``:'' 073 ``;'' 074 ``<'' 075 ``='' 076 ``>''
077 ``?'' 100 ``@'' 101 ``A'' 102 ``B'' 103 ``C''
104 ``D'' 105 ``E'' 106 ``F'' 107 ``G'' 110 ``H''
111 ``I'' 112 ``J'' 113 ``K'' 114 ``L'' 115 ``M''
116 ``N'' 117 ``O'' 120 ``P'' 121 ``Q'' 122 ``R''
123 ``S'' 124 ``T'' 125 ``U'' 126 ``V'' 127 ``W''
130 ``X'' 131 ``Y'' 132 ``Z'' 133 ``['' 134 ``''
135 ``]'' 136 ``^'' 137 ``_'' 140 ```'' 141 ``a''
142 ``b'' 143 ``c'' 144 ``d'' 145 ``e'' 146 ``f''
147 ``g'' 150 ``h'' 151 ``i'' 152 ``j'' 153 ``k''
154 ``l'' 155 ``m'' 156 ``n'' 157 ``o'' 160 ``p''
161 ``q'' 162 ``r'' 163 ``s'' 164 ``t'' 165 ``u''
166 ``v'' 167 ``w'' 170 ``x'' 171 ``y'' 172 ``z''
173 ``{'' 174 ``|'' 175 ``}'' 176 ``~''
RETURN VALUES
The isgraph() function returns zero if the character tests false and returns non-zero if the character tests true.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The iswgraph() function should be used instead.
SEE ALSO ctype(3), isalnum_l(3), iswgraph(3), ascii(7)STANDARDS
The isgraph() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
