Hi,
How can I edit a line in a file?
For example, a.txt contains:

setcap
SETCAP(8) System Manager's Manual SETCAP(8)NAME
setcap - set file capabilities
SYNOPSIS
setcap [-q] [-v] (capabilities|-|-r) filename [ ... capabilitiesN fileN ]
DESCRIPTION
In the absence of the -v (verify) option setcap sets the capabilities of each specified filename to the capabilities specified. The -v
option is used to verify that the specified capabilities are currently associated with the file.
The capabilities are specified in the form described in cap_from_text(3).
The special capability string, '-', can be used to indicate that capabilities are read from the standard input. In such cases, the capabil-
ity set is terminated with a blank line.
The special capability string, '-r', is used to remove a capability set from a file.
The -q flag is used to make the program less verbose in its output.
EXIT CODE
The setcap program will exit with a 0 exit code if successful. On failure, the exit code is 1.
