I have stumbled upon very unique issue. In my script I am doing cat file and then greping and cutting so as to assign the value to variable. My file is,
This command did not work and gives error as
cat: cannot open mxc_tl_load_extractdata_prop.bsh
But in the same script after above command next variable "hostname" is able to be extracted (with exact same command) and is assigned to variable.
The script worked on "SunOS 5.8 Generic_117350-55 sun4us sparc FJSV,GPUZC-Land" but issue is coming on "SunOS 5.10 Generic_137111-04 sun4u sparc SUNW,SPARC-Enterprise"
I have alrady checked for white space issue.
Can anybody help?
Regards

Not sure how to do this exactly.. just want to take the first 100 lines of a file and cat it out into a second file. I know I can do a more on a file and > it into a different file, but how can I make it so only the first 100 lines get moved over? (1 Reply)

Hi,
I am not being able to open txt files with 'cat'. One thing to mention is, the filenames start with #. I guess one can have a unix filename that starts with a special/wildcard character. I have filenames starting with @ and they are opening perfectly with cat. (5 Replies)
Hello,
I'm on a remote computer by SSH. How can I get the output of "cat file" into a file on the local computer?
I cannot use scp, because it's blocked.
something like:
ssh root@remote_maschine "cat /file" > /locale_machine/file

truncate - shrink or extend the size of a file to the specified size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole)
reads as zero bytes.
Mandatory arguments to long options are mandatory for short options too.
-c, --no-create
do not create any files
-o, --io-blocks
treat SIZE as number of IO blocks instead of bytes
-r, --reference=RFILE
base size on RFILE
-s, --size=SIZE
set or adjust the file size by SIZE
--help display this help and exit
--version
output version information and exit
SIZE may be (or may be an integer optionally followed by) one of following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T,
P, E, Z, Y.
SIZE may also be prefixed by one of the following modifying characters: `+' extend by, `-' reduce by, `<' at most, `>' at least, `/' round
down to multiple of, `%' round up to multiple of.
