How would one go about deleting the first two characters on each line of a file on Unix? I thought about using awk, but cannot seem to find if it can explicitly do this. In this case there might or might not be a field separator. Meaning that the data might look like this.

Is it possible to do the following in a single command
/usr/xpg4/bin/sed -e '/rows selected/d' /aemu/CALLAUTO/callauto.txt > /aemu/CALLAUTO/callautonew.txt

Hi,
I was trying to remove the blank from beginning of a line.
when I try:
sed 's/^ +//' filename
it does not work
but when I try
sed 's/^ *//' filename
it works
But I think the first command should have also replaced any line with one or more blanks.
Kindly help me in understanding... (5 Replies)

ucblinks(1B) SunOS/BSD Compatibility Package Commands ucblinks(1B)NAME
ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices
SYNOPSIS
/usr/ucb/ucblinks [-e rulebase] [-r rootdir]
DESCRIPTION
ucblinks creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.
ucblinks does not remove unneeded compatibility links; these must be removed by hand.
ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been created,
since the reconfiguration may have resulted in more compatibility names being needed.
In releases prior to SunOS 5.4, ucblinks used a nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses nawk
for the default operation, although nawk rule-bases can still be specifed with the -e option. The nawk rule-base equivalent to the SunOS
5.4 default operation can be found in /usr/ucblib/ucblinks.awk.
OPTIONS -e rulebase Specify rulebase as the file containing nawk(1) pattern-action statements.
-r rootdir Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.
