Твой это:
ps auxw | grep [PROCESS-NAME] | awk '' | xargs strace
Как реализовать скрипт оболочки pstrace
в bash, который изменяет интерфейс
[sudo] strace -c -p [PID]
в
[sudo] pstrace -c -p [PROCESS-NAME]
похоже на то, как
killall [PROCESS-NAME]
используется. С завершением и всем.
Твой это:
ps auxw | grep [PROCESS-NAME] | awk '' | xargs strace
Deceptively complicated requirements :-)
In two parts, firstly the pstrace
wrapper script for strace
, this uses pgrep
for the name-to-PID operation.
#!/bin/bash IFS=$' \t\n' # process the arguments to find "-p procname", only support one instance though for ((nn=1; nn<=$#; nn++)); do if [ "${!nn}" = "-p" ]; then : elif [ "$prev" = "-p" ]; then pname="${!nn}" else args+=( "${!nn}" ) # just copy fi prev="${!nn}" done pids=() if [ -n "$pname" ]; then # skip this shell's PID, which pgrep -f will match # note the use of exec to avoid picking up a matching subshell too # uncomment && printf for pid/pname list while read pp pname; do [ "$pp" != "$$" ] && pids+=($pp) # && printf "%6i %s\n" "$pp" "$pname" done < <(exec pgrep -l -f "$") fi npids=${#pids[*]} if [ $npids -eq 0 ]; then echo "No PIDs to trace."; exit 2 elif [ $npids -eq 1 ]; then args=( "$" -p $ ) elif [ $npids -le 32 ]; then read -p "$npids PIDS found, enter Y to proceed: " yy [ "$yy" != "Y" ] && echo "Cancelled..." && exit 1 args=( "$" $ ) else echo "Too many PIDs to trace: $npids (max 32)."; exit 2 fi strace "$"
For the second part I'll use bash
programmable completion to complete processes by name, put this in your ~/.bash_profile
or similar:
# process-name patterns to ignore PROCIGNORE=( "^\[", "^-bash" ) _c8n_listprocs () { local cur prv ignore IFS nn mm prv=$ cur=$ case "$prv" in '-p') IFS=$'\n' COMPREPLY=( $(ps axwwo "args") ) IFS=$' \t\n' COMPREPLY=($) # remove arguments ignore="0" # ps header for ((nn=1; nn<${#COMPREPLY[*]}; nn++)); do # filter by (partially) typed name in cur # use " =~ ^$cur " for prefix match, without ^ it's substr match [[ -n "$cur" && ! "$" =~ $cur ]] && { ignore="$nn $ignore" } || { # skip names matching PROCIGNORE[] for ((mm=0; mm<${#PROCIGNORE[*]}; mm++)); do [[ "$" =~ $ ]] && ignore="$nn $ignore" done } done # remove unwanted, in reverse index order for nn in $ignore; do unset COMPREPLY[$nn]; done ;; *) COMPREPLY=() ;; esac } complete -F _c8n_listprocs pstrace
Tested & used on linux with bash-3.x and bash-4.x. ps
options may need tweaking on non-Linux platforms, should also support truss
with a one-line change.
Limitations include:
[names]
, this will cause pgrep
to (likely) not do what you wantargs
" is used instead of "comm
" so that /paths
can be used, where available)
